Figure 2.

Mean percentage of bias in the estimated relative excess risk due to interaction (RERI) across exposure/outcome scenarios and cluster sizes, by model type, for scenarios described in Table 1. A) Scenario 3; B) scenario 4; C) scenario 5; D) scenario 6; E) scenario 7; F) scenario 8; G) scenario 9; H) scenario 10; I) scenario 11. See Table 1 for the full scenario descriptions. The squares represent results for the Bayesian log binomial random intercept with a half-Cauchy(0, 5) prior distribution on the standard deviation (SD) for the random intercepts; the circles represent results for the Bayesian log binomial random intercept with a gamma(2, 0.1) prior distribution on the SD; the triangles represent results for the frequentist fit of the log binomial random intercept model; and the diamonds represent results for the frequentist fit of the Poisson random-intercept model. Note that some scenarios/clusters do not have symbols for the frequentist models because there were no models that converged and had nondegenerate SD estimates under these fits.
