- Twenty-nine teams involving 61 analysts used the same dataset to address the same research question: whether soccer referees are more likely to give red cards to dark skin toned players than light skin toned players. Analytic approaches varied widely across teams, and estimated effect sizes ranged from 0.89 to 2.93 in odds ratio units, with a median of 1.31. Twenty teams (69%) found a statistically significant positive effect and nine teams (31%) observed a non-significant relationship. Overall 29 differentanalyses used 21 unique combinations of covariates. We found that neither analysts' prior beliefs about the effect, nor their level of expertise, nor peer-reviewed quality of analysis readily explained variation in analysis outcomes. This suggests that significant variation in the results of analyses of complex data may be difficult to avoid, even by experts with honest intentions. Crowdsourcing data analysis, a strategy by which numerous research teams are recruited to simultaneously investigate the same research question, makes transparent how defensible, yet subjective analytic choices influence research results.

- Aim of the study: Oesophageal and gastric varices are well-known causes of morbidity and mortality in patientswith liver cirrhosis. The aim of this retrospective observational study was to analyse clinical characteristics andoutcomes for patients with oesophageal and gastric varices at Norrland’s University Hospital, Umeå, Sweden.Material and methods: Data from medical records were collected retrospectively from 246 patients with oesophageal and gastric varices between 2006 and 2019.Results: At the end of the study 60.1% of the patients had died at a median age of 69 years (range 26-95).Mortality of patients with gastro-oesophageal varices was significantly greater than that of the general population. Median survival from the time of variceal diagnosis was 59 months (confidence interval [CI] 95%:45-73 months). Five-year and 10-year cumulative survival rates in the entire cohort were 49.7% and 27.7%,respectively, with no sex-related differences. The highest mortality rate was seen in alcoholic cirrhosis with concomitant hepatitis. Mortality was higher in Child-Turcotte-Pugh (CTP) B and C compared to CTP A. Liver failureand liver cancer were the most common causes of death (43.8%). Thirty-one percent of the patients had avariceal haemorrhage. Eleven percent were subjected to liver transplantation, whereas 3.9% of the patients had beensubmitted to a transjugular intrahepatic portosystemic shunt (TIPS) procedure.Conclusions: Despite the latest therapeutic advances, the survival of patients with gastro-oesophageal varicesremains significantly reduced. All-cause mortality was significantly related to CTP class, aetiology, occurrence ofvariceal bleeding, whether variceal bleeding was the primary symptom and whether patients had undergoneliver transplantation or not.
