Sex was also related to the performance in the FCSRT, with women outperforming men. Equations to calculate z-scores and normative percentile tables were created. As compared with previously published norms the reference data presented were more sensitive but less specific, as expected.The use of the norms provided in this work, in combination with the already published conventional norms, may contribute to detecting subtle memory impairment.

- Cognitive performance of a given individual should be interpreted in the context of reference standards obtained in cognitively healthy populations.
