Fig. 4: Estimated ORs and 95% CIs of poor self-rated health, ADL and IADL limitations across quintiles of IC score (Q1 lowest to Q5 highest).

Logistic regression models were used to examine the associations between quintiles of IC scores and three established measures for self-rated health (N = 60,254), ADL (N = 60,258) and IADL (N = 60,201) limitations, adjusting for age group, sex, education, MPCE, place of residence, marital status and multimorbidity. ORs are shown as the center points with 95% CIs as error bars. Q, quintile.
