- Replication studies in psychological science sometimes fail to reproduce prior findings. If these studies use methods that are unfaithful to the original study or ineffective in eliciting the phenomenon of interest, then a failure to replicate may be a failure of the protocol rather than a challenge to the original finding. Formal pre-data-collection peer review by experts may address shortcomings and increase replicability rates. We selected 10 replication studies from the Reproducibility Project: Psychology (RP:P; Open Science Collaboration, 2015) for which the original authors had expressed concerns about the replication designs before data collection; only one of these studies had yielded a statistically significant effect (p < .05). Commenters suggested that lack of adherence to expert review and low-powered tests were the reasons that most of these RP:P studies failed to replicate the original effects. We revised the replication protocols and received formal peer review prior to conducting new replication studies. We administered the RP:P and revised protocols in multiple laboratories (median number of laboratories per original study = 6.5, range = 3-9; median total sample = 1,279.5, range = 276-3,512) for high-powered tests of each original finding with both protocols. Overall, following the preregistered analysis plan, we found that the revised protocols produced effect sizes similar to those of the RP:P protocols (Delta r = .002 or .014, depending on analytic approach). The median effect size for the revised protocols (r = .05) was similar to that of the RP:P protocols (r = .04) and the original RP:P replications (r = .11), and smaller than that of the original studies (r = .37). Analysis of the cumulative evidence across the original studies and the corresponding three replication attempts provided very precise estimates of the 10 tested effects and indicated that their effect sizes (median r = .07, range = .00-.15) were 78% smaller, on average, than the original effect sizes (median r = .37, range = .19-.50).

- Aims Trials demonstrate that following the DASH diet lowers blood pressure, which may prevent the development of heart failure (HF). We investigated the association between long-term adherence to the DASH diet and food substitutions within the DASH diet on the risk of HF. Methods and results Men and women aged 45-83 years without previous HF, ischaemic heart disease or cancer at baseline in 1998 from the Cohort of Swedish Men (n = 41 118) and the Swedish Mammography Cohort (n = 35 004) were studied. The DASH diet emphasizes intake of fruit, vegetables, whole grains, nuts and legumes, and low-fat dairy and deemphasizes red and processed meat, sugar-sweetened beverages, and sodium. DASH diet scores were calculated based on diet assessed by food frequency questionnaires in late 1997 and 2009. Incidence of HF was ascertained using the Swedish Patient Register. Multivariable Cox proportional hazards models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs). During the median 22 years of follow-up (1998-2019), 12 164 participants developed HF. Those with the greatest adherence to the DASH diet had a lower risk of HF compared to those with the lowest adherence (HR 0.85, 95% CI: 0.80, 0.91 for baseline diet and HR 0.83, 95% CI: 0.78, 0.89 for long-term diet, comparing quintiles). Replacing 1 serving/day of red and processed meat with emphasized DASH diet foods was associated with an 8-12% lower risk of HF. Conclusion Long-term adherence to the DASH diet and relevant food substitutions within the DASH diet were associated with a lower risk of HF.

- Background A previous study found that consuming 5 or more cups of coffee per day was associated with increased incidence of heart failure (HF). We sought to evaluate this association in a larger population. Methods We measured coffee consumption using food frequency questionnaires among 37,315 men without history of myocardial infarction, diabetes, or HE They were observed for HF hospitalization or mortality from January 1, 1998, until December 3 1, 2006, using record linkage to the Swedish inpatient and cause of death registries. Cox proportional hazards models adjusted for age, dietary, and demographic factors were used to calculate incidence rate ratios (RR) and 95% confidence intervals (CIs). Results For 9 years of follow-up, 784 men experienced an HF event. Compared to men who drank! l cup of coffee per day (unadjusted rate 29.9 HF events/ 10,000 person-years), RR were 0.87 (95% CI 0.69-1.11, unadjusted rate 29.2/10,000 person-years) for 2 cups/d, 0.89 (95% CI 0.70-1.14, unadjusted rate 25.1/10,000 person-years) for 3 cups/d, 0.89 (95% CI 0.69-1.15, unadjusted rate 25.0/10,000 person-years) for 4 cups/d, and 0.89 (95% CI 0.69-1.15, unadjusted rate 18.1/10,000 person-years) for >= 5 cups/d (P for trend in RR = .61). Conclusions This study did not support the hypothesis that high coffee consumption is associated with increased rates of HF hospitalization or mortality. (Am Heart J 2009;158:667-72.)

- Background Compared with no alcohol consumption, heavy alcohol intake is associated with a higher rate of heart failure (HF) whereas light-to-moderate intake may be associated with a lower rate. However, several prior studies did not exclude former drinkers, who may have changed alcohol consumption in response to diagnosis. This study aimed to investigate the association between alcohol intake and incident HF. Methods and Results We conducted a prospective cohort study of 33 760 men aged 45 to 79 years with no HF, diabetes mellitus, or myocardial infarction at baseline participating in the Cohort of Swedish Men Study. We excluded former drinkers. At baseline, participants completed a food frequency questionnaire and reported other characteristics. HF was defined as hospitalization for or death from HF, ascertained by Swedish inpatient and cause-of-death records from January 1, 1998, through December 31, 2011. We constructed Cox proportional hazards models to estimate multivariable-adjusted incidence rate ratios. During follow-up, 2916 men were hospitalized for (n=2139) or died (n=777) of incident HF. There was a U-shaped relationship between total alcohol intake and incident HF (P=0.0004). There was a nadir at light-to-moderate alcohol intake: consuming 7 to <14 standard drinks per week was associated with a 19% lower multivariable-adjusted rate of HF compared with never drinking (incidence rate ratio, 0.81; 95% confidence interval, 0.69-0.96). Conclusions In this cohort of Swedish men, there was a U-shaped relationship between alcohol consumption and HF incidence, with a nadir at light-to-moderate intake. Heavy intake did not seem protective.

- AimThe impact of the anti‐inflammatory potential of diet on risk of heart failure (HF) and the potential modification of this association by smoking, a trigger of systemic inflammation, has not been previously investigated. We examined the association between anti‐inflammatory potential of diet and risk of HF taking into account smoking status.Methods and resultsThe study population included the Cohort of Swedish Men (40 514 men) and the Swedish Mammography Cohort (34 809 women), age 45–83 years, without HF, ischaemic heart disease, or cancer at baseline. Anti‐inflammatory potential of diet was estimated using an anti‐inflammatory diet index (AIDI; 0–16 scores). Cox proportional hazard regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) adjusted for HF risk factors. Over a mean follow‐up of 14.9 years (1 119 110 person‐years, 1998–2014), 8161 new HF diagnoses (4443 in men, 3718 in women) were identified. Compared to the lowest quintile of the AIDI (scores ≤4), the HRs for men and women in the highest quintile (scores ≥8) were 0.92 (95% CI 0.84–1.02; P‐trend = 0.02) and 0.86 (95% CI 0.78–0.96; P‐trend = 0.001), respectively. An inverse association between the AIDI and HF incidence was observed in current and ex‐smokers but not in never‐smokers (P‐interaction = 0.046). Comparing extreme quintiles, the HRs were 0.86 (95% CI 0.74–1.00; P‐trend = 0.007) in current smokers, 0.81 (95% CI 0.71–0.92; P‐trend = 0.001) in ex‐smokers, and 0.95 (95% CI 0.86–1.06; P‐trend = 0.10) in never‐smokers.ConclusionThese results suggest that adherence to a diet with high anti‐inflammatory potential may be associated with lower HF incidence in current and ex‐smokers.

- The authors examined the association of dietary calcium and magnesium intake with all-cause, cardiovascular disease (CVD), and cancer mortality among 23,366 Swedish men, aged 45-79 years, who did not use dietary supplements. Cox proportional hazards regression models were used to estimate the multivariate hazard ratios and 95% confidence intervals of mortality. From baseline 1998 through December 2007, 2,358 deaths from all causes were recorded in the Swedish population registry; through December 2006, 819 CVD and 738 cancer deaths were recorded in the Swedish cause-of-death registry. Dietary calcium was associated with a statistically significant lower rate of all-cause mortality (hazard ratio (HR) = 0.75, 95% confidence interval (CI): 0.63, 0.88; P-trend < 0.001) and a nonsignificantly lower rate of CVD (HR = 0.77, 95% CI: 0.58, 1.01; P-trend = 0.064) but not cancer mortality (HR = 0.87, 95% CI: 0.65, 1.17; P-trend = 0.362) when the highest intake tertile (mean = 1,953 mg/day; standard deviation (SD), 334) was compared with the lowest (990 mg/day; SD, 187). Dietary magnesium intake (means of tertiles ranged from 387 mg/day (SD, 31) to 523 mg/day (SD, 38) was not associated with all-cause, CVD, or cancer mortality. This population-based, prospective study of men with relatively high intakes of dietary calcium and magnesium showed that intake of calcium above that recommended daily may reduce all-cause mortality.

- Background-Obesity is associated with heart failure (HF) incidence. We examined the strength of the association of body mass index (BMI) with HF by age and joint associations of BMI and waist circumference (WC). Methods and Results-Women aged 48 to 83 (n=36 873) and men aged 45 to 79 (n=43 487) self-reported height, weight, and WC. HF hospitalization or death (n=382 women, 718 men) between January 1, 1998, and December 31, 2004, was determined through administrative registers. Hazard ratios, from Cox proportional-hazards models, for an interquartile range higher BMI were 1.39 (95% CI, 1.15 to 1.68) at age 60 and 1.13 (95% CI, 1.02 to 1.27) at 75 in women. In men, hazard ratios were 1.54 (95% CI, 1.37 to 1.73) at 60 and 1.25 (95% CI, 1.16 to 1.35) at 75. A 10-cm higher WC was associated with 15% (95% CI, 2% to 31%) and 18% (95% CI, 4% to 33%) higher HF rates among women with BMI 25 and 30 kg/m(2), respectively; hazard ratios for 1 kg/m(2) higher BMI were 1.00 (95% CI, 0.96 to 1.04) and 1.01 (95% CI, 0.98 to 1.04) for WC 70 and 100 cm, respectively. In men, a 10-cm higher WC was associated with 16% and 18% higher rates for BMI 25 and 30 kg/m(2), respectively; a 1 kg/m(2) higher BMI was associated with 4% higher HF rates regardless of WC. Conclusions-Strength of the association between BMI and HF events declined with age. In women, higher WC was associated with HF at all levels of BMI. Both BMI and WC were predictors among men.

Tidskriftsartikel (refereegranskat)abstract
- alpha-Linolenic acid (18: 3n-3) intake and linoleic acid (18: 2n-6) intake have been associated with lower rates of CHD, though results have not been consistent. The relationship of these fatty acids with incident heart failure (HF) is not well established. We examined the hypothesis that women with higher intakes of 18: 3n-3 and 18: 2n-6 would have lower rates of HF hospitalisation and mortality. We measured 18 : 3n-3 and 18: 2n-6 intake in 36 234 Swedish Mammography Cohort participants aged 48-83 years using FFQ and followed participants through Swedish inpatient and cause-of-death registers from 1 January 1998 until 31 December 2006. Cox models were used to calculate incidence rate ratios (RR) and 95% CI. Because of multicollinearity, 18: 3n-3 and 18: 2n-6 were examined separately. Over 9 years, 596 women were hospitalised and fifty-five died due to HF. In models accounting for age and other covariates, the RR for HF comparing the top quintile of 18 : 3n-3 (median 1.50 g/d) with the bottom quintile (median 0.88 g/d) was 0.91 (95% CI 0.71, 1.17, P-trend = 0.41). The RR comparing the top quintile of 18: 2n-6 (median 7.8 g/d) with the bottom quintile (median 4.6 g/d) was 1.14 (95% CI 0.88, 1.46, P-trend = 0.36). We did not find evidence for the interaction of 18: 3n-3 and 18: 2n-6 with each other or with long-chain n-3 fatty acids. In conclusion, these data do not support our hypothesis that 18: 3n-3 and 18: 2n-6 are associated with HF. However, these results may not be generalisable to populations with higher intakes of 18: 3n-3.

- Background-Previous studies of the relationship between coffee consumption and incidence of heart failure (HF) have not been consistent, with both potential benefit and potential harm reported. We therefore examined the association between coffee consumption and HF hospitalization or mortality in women. Methods and Results-We conducted a prospective, observational study of 34 551 participants of the Swedish Mammography Cohort who were 48 to 83 years old and did not have HF, diabetes, or myocardial infarction at baseline. Diet was measured using food-frequency questionnaires. Cox models were used to calculate hazard ratios of HF hospitalization or death from HF as the primary cause, as determined through the Swedish inpatient and cause-of-death registers between January 1, 1998, and December 31, 2006. Over 9 years of follow-up, 602 HF events occurred. Women who consumed >= 5 cups of coffee per day did not have higher rates of HF events than those who consumed <5 cups per day (multivariable-adjusted hazard ratio, 0.93; 95% confidence interval, 0.72 to 1.20). Compared with women who consumed <= 1 cup of coffee per day, hazard ratios were 1.01, 0.82, 0.94, and 0.87 for women who consumed 2, 3, 4, and >= 5 cups per day, respectively (P for trend =0.23). Further adjustment for self-reported hypertension did not change the results. Conclusions-In this population of middle-aged and older women, we did not find an association between coffee consumption and incidence of HF events. (Circ Heart Fail. 2011; 4: 414-418.)

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The Dietary Approaches to Stop Hypertension (DASH) diet effectively reduces blood pressure. In observational studies, the association between diets consistent with DASH and risk of coronary heart disease and stroke has been examined with varying results. We hypothesized that diets consistent with the DASH diet would be associated with a lower incidence of heart failure (HF).METHODS: We conducted a prospective observational study in 36 019 participants in the Swedish Mammography Cohort who were aged 48 to 83 years and without baseline HF, diabetes mellitus, or myocardial infarction. Diet was measured using food-frequency questionnaires. We created a score to assess consistency with the DASH diet by ranking the intake of DASH diet components and 3 additional scores based on food and nutrient guidelines. Cox proportional hazards models were used to calculate rate ratios of HF-associated hospitalization or death, determined using the Swedish inpatient and cause-of-death registers between January 1, 1998, and December 31, 2004.RESULTS: During 7 years, 443 women developed HF. Women in the top quartile of the DASH diet score based on ranking DASH diet components had a 37% lower rate of HF after adjustment for age, physical activity, energy intake, education status, family history of myocardial infarction, cigarette smoking, postmenopausal hormone use, living alone, hypertension, high cholesterol concentration, body mass index (calculated as weight in kilograms divided by height in meters squared), and incident myocardial infarction. Rate ratios (95% confidence intervals) across quartiles were 1 [Reference], 0.85 (0.66-1.11), 0.69 (0.54-0.88), and 0.63 (0.48-0.81); P(trend) < .001. A similar pattern was seen for the guideline-based scores.CONCLUSION: In this population, diets consistent with the DASH diet are associated with lower rates of HF.
