Sensitivity plots of relative risks for a randomized controlled trial accounting for all possible missing outcome (live birth and positive pregnancy test (PPT)) scenarios. Percent of missing allocated to positive outcome within the aspirin and placebo treatment arms is displayed on the x- and y-axis, respectively. Trial results are displayed overall (first column) and stratified by two block randomized eligibility strata (original – second column, and expanded – third column). The dotted line (white region) depicts the percent of missing allocated positive outcome in each group for the overall trial results to be null (relative risk, RR = 1.0); increasing darker gradation reflects further departures from the null. The full plot encompasses any potential mechanism, including MNAR.
