a Coefficients for the “initial status” show the difference in mean PF-10 score at baseline between the respective categories and the reference category.
b Coefficients for the “slope” indicate the difference in the mean annual PF-10 score change between the respective categories and the reference category.
c Per 1-unit increase (centered on the value 9)
Model 1: adjusted for baseline age centred at 58 years (and country cohort in case of the pooled sample)
Model 2: adjusted for baseline age centred at 58 years, smoking, marital status, education, ownership of household items, economic activity, joint/spine problem (and country cohort in case of the pooled sample)
