  1. Linear mixed-effects regression model with inverse probability weighting, crude model and adjusted model for selected demographic characteristics, comorbidities and comedication (details in methods). Coefficient for the point-wise difference in MMSE points over time between comparison groups, 95% CI and two-sided p-values are reported. Average refers to the average difference in MMSE points between comparison groups at any time point
