Fig. 4 — Points represent the regression coefficients of the linear models and bars the 95% confidence intervals. The PDQ-39 domains were standardized in order to make the estimates comparable. Higher PDQ-39 domain scores represent worse experienced quality of life. Models were adjusted for sex, age, disease duration, presence of comorbidities, education, living situation, region, and date. N = 844.
