PHYSICAL ILLNESS
We added age, physical illness at baseline, education, cognitive impairment, and sex as covariates in the model to explore whether these factors predicted or moderated outcomes of the main analysis. Age at baseline was added as a continuous variable. Sex was added as a dichotomous variable indicating whether someone was male or female. Education was added as a continuous variable ranging from 1 (no to primary education) to 6 (university degree). MoCA was added as a continuous variable in the model. To plot the effect of MoCA on WHODAS scores over time, we dichotomised between mild cognitive impairment (MoCA = 18–25) or no cognitive impairment (MoCA ≥ 26).
