Highest socioeconomic position in education, income, and occupation index was referent (1.0), respectively. Duncan's post-hoc test is implemented to compare ground differences. Same alphabetical letters indicates no statistical differences between two mean values. Morbidity (0 = lowest, 1 = highest).
