Abbreviations: BCI, bootstrap confidence interval; RD, risk difference.

^aThe authors assumed that the sensitivity functions followed linear structures, such that c(z = 1, e) = c₁ + s₁e and c(z = 0, e) = r × (z = 1, e).

^bThe 95% bootstrap confidence intervals were obtained using the 2.5% and 97.5% percentiles among the 1,000 bootstrap replications.
