1 Results from two mixed regression models are presented. Both groups were balanced. Coef.: Coefficient; CI: Confidence Interval; Ref.: Reference Category; * age and depression (depend variable) are time varying variables, all the other variables are time-invariant. The bold type shows the reader at first glance which factors are significant.
