Table 2 Mean physical, affective, and cognitive functioning at baseline and six-year follow-up phase, according to adult occupational level, adjusted for age and sex (analysis of variance); mean six-year functional change score is additionally adjusted for baseline functioning (analysis of variance) (N = 1211)a
