  1. aNumber of participants (n), differs between rows due to missing values; b Clock-drawing test [14] results indicate a global cognitive function. Scores can range from 0 to 6 and higher score indicates better cognitive function; c Continuous variables: P value for t-test (Age, Age when left full time education, BMI, Clock-drawing); Ordinal variables: P value for Mann-Whitney U test (Age category, Self-rated health); Binary variables: P value for chi-square test (all other variables)
