ICC for immunisation was 0.05 (95% CI 0.024 to 0.102); MOR=1.5. Conditional ICC of the final model=0.026, MOR=1.32.
(MOR is a measure of residual cluster-level heterogeneity. When we compare two children from randomly chosen different clusters, with the same covariates, MOR is the MOR between the child of higher odds and child of lower odds.)
ICC, intracluster correlation coefficient; MOR, median OR; OBC, other backward class; PUHC, Primary Urban Health Centre; SC, scheduled caste; ST, scheduled tribe.
