Notes: SRH = self-rated health; EURO-D = EURO-D scale for depression. Estimates are fully standardized (β). Reference individual is a 65-year-old male, living in a Bismarckian country with upper secondary education (ISCED-3), a low-skill job, and not part of a refreshment sample. Confidence intervals (CIs) based on robust standard errors.
