Comparing the 12-month models using decision curve analysis, net benefit is plotted versus threshold probability of 12-month survival. All models (ANN, BBN, logistic regression [LOGIT]) resulted in positive net benefit, indicating they could be used clinically rather than assume all patients (or no patients) will survive longer than 12 months after surgery. Note the ANN outperformed the other models across all threshold probabilities, including the clinically useful threshold probability of 50% estimated survival at 12 months.
