Distribution of the overall conclusions and errors, obtained by applying the decision rule to the 5000 simulated trials, according to the event and the scenario. This plot presents the overall numbers or misclassifications obtained by applying this decision rule, according to the 5 scenario and to the 4 events. The left part of the plot represents the trials with an Acceptable difference between arms: orange area correspond to trials that conclude that the difference between arms is Acceptable, while it is true; red area correspond to trials that conclude that the difference between arms is Unacceptable, while it is not true (class a misclassifications). The right part of the plot represents the trials with an Unacceptable difference between arms: green area correspond to trials that conclude that the difference between arms is Unacceptable, while it is true; blue area correspond to trials that conclude that the difference between arms is Acceptable, while it is not true (class b misclassifications). IVH: Intraventricular haemorrhage; NEC: Necrotizing enterocolitis
