bAll bivariate regressions included study site fixed effects and interviewer random intercepts. Values for male and female IVR are marginal predicted values based on regression coefficients. c ICC is the proportion of all variance in a model without interviewer gender attributable to variation in interviewer identity; not available for Poisson or ordered logistic models.. P-value is for a χ2 test, adjusted for multiple testing across all results shown in Tables 1, 2, 3 and 4 using the Benjamini-Hochberg method
