Coverage of 95 % confidence intervals for the log odds ratio of a household-level predictor. The lines correspond to coverage of confidence intervals that adjust for clustering at the village-level, household-level or do not adjust for clustering. Coverage is presented as a function of the degree of village-level clustering in the outcome as measured by the intra-cluster correlation (ICC). The intra-cluster correlation of the predictor ranges between 0 (top) and 1 (bottom), for K=5 (left) or K=20 (right) villages. The remaining parameter values are α 0=log(0.1/0.9), α 1=σ h =log(2), I=5, J=20
