aWe used the Mini-Cog algorithm for scoring abnormal performance on clock drawing test (CDT). Specifically, “The CDT is considered normal if all the numbers are present in the correct sequence and position, and the hands readably display the requested time.” [52].
bAbnormal Trails B result defined as completion time of >3 min or ≥3 errors [53]. n=120 cases included the Trails B data.
