Performance of MP (a) estimates (black line) and MP estimates (blue dotted line) when changing baseline outcome prevalence from 1% to 50% in Case #4, where sample size is 20,000. Bias(%), CR (d), and VR denote the percent bias, coverage rate by the multivariate delta method, and variance ratio. Upper row: results for TE=log(1.2) and MP=0.1; second row: results for TE=log(1.2) and MP=0.5; third row: results for TE=log(2) and MP=0.1; bottom row: results for TE=log(2) and MP=0.5
