Figure 1. Difference in power relative to unweighted t-test (one rainy season).

Figure 1.

Single-year graphs indicating the difference in one-sided power (in favor of protective ivermectin effect) for the three analysis frameworks, mixed-effects models (MM), generalized estimating equations (GEE), and cluster-level summaries relative to the unweighted t-test for a range of rate ratios. A rate ratio of 1 reflects the null model. The first rate ratio of approximately 0.56 reflects the expected rate ratio for RIMDAMAL II.
