We processed 4768 of the 4840 driving license renewal visits carried out at the University of Milan from May 2011 to March 2017 (reason for exclusion: subject < 80 years old). Inconsistencies in visit information were corrected (see Additional file1– Materials and methods - Selection of subjects and eTable 3). Overall, there were 3392 (71.14%) first visits, 945 (19.82%) second visits, 307 (6.44%) third visits, 92 (1.93%) fourth visits, 29 (0.61%) fifth visits, 2 (0.04%) sixth visits, and only 1 (0.02%) seventh visit.

In the current paper, we based our analysis on 4241 first and second visits, including 3378 first visits where the MMSE test was administered (99.59% of all first visits, 89.74% of all MMSE tests administered) and 863 second visits where the MoCA was administered (91.32% of all second visits, 85.96% of all MoCA tests administered) (reasons for exclusion: in 14 first visits MoCA was administered and in 82 second visits MMSE was administered, see eTable 3).
