Flow-chart of the DanACo cohort. Abbreviations: LiKO-15: Lifestyle and Cognition Follow-up study 2015; DiaKO-19: Diabetes and Cognition Follow-up study 2019; DanACo: Danish Aging and Cognition. The included percentages were calculated as proportions of the number of men invited to the LiKO-15 and DiaKO-19 studies, respectively. For LiKO-15, the percentages marked with * are calculated based on the total number of participants invited from the Psychiatric database and the Danish Conscription Database. ^†As 3,805 of the LiKO-15 non-participants were also invited to the DiaKO-19 study, the total number of non-participants in the DanACo cohort, 37,444 men, is equal to the combined number of non-participants from the LiKO-15 and DiaKO-19 studies (35,909) minus the 3,805 participants that were invited twice
