Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.

PSS000451 Chronotype was assessed using a singl self-evaluatation question from a shortend version of Horne and Ostber'gs MEQ (sMEQ) on chronotype. The sMEQ included 6 items (items 4,7,9,15,17 and 19) from the original MEQ. The answers were scored according to the scoring of the original MEQ. For the single self-evaluation question item 19 was used. The question was used as a binary varable in which those who replied either "rather more an evening than a morning type" or "definitely an evening type" were regarded as evening types, and those who replied "definitely a morning type" or "rather more a morning type than an evening type" were regarrded as morning types. —

PSS000452 Chronotype was assessed using a shortend version of Horne and Ostberg's MEQ(sMEQ) . The sMEQ included 6 items (items 4,7,9,15,17 and 19) from the original MEQ. The answers were scored according to the scoring of the original MEQ. The sum score was used as a binary variable (evening type: socres from 5-15, morning type: socres from 16 to 27; binary sMEQ score). —

PSS000453 Chronotype was assessed using a shortend version of Horne and Ostberg's MEQ(sMEQ) The sMEQ included 6 items (items 4,7,9,15,17 and 19) from the original MEQ. The answers were scored according to the scoring of the original MEQ. The sum score was used as a continuous variable (continuous sMEQ score). — 7,436 individuals — European
