Clinical simulation with accuracies of predictions as a function of excluding uncertain electrocardiograms on the in-distribution setting of the UMCU-Triage dataset. The threshold percentage corresponds to the percentage of data that needs to be evaluated by a physician after exclusion. Through excluding uncertain electrocardiograms, accuracy of all models improved. The VI+BD model had the steepest upward slope, and thus excluded the uncertain electrocardiograms the fastest, thereby increasing overall model accuracy at the highest rate.
