*Model 0: crude. Model 1: Model 0 adjusted for the other two socioeconomic variables. Model 2: Model 1 adjusted for sex and age. Model 3: Model 2 adjusted for sex, age and the Charlson Comorbidity Index. Model 4: Model 3 adjusted for family structure, type of house, civil status and region of residence.
