From: A nomogram for predicting cancer-specific survival for elderly patients with gallbladder cancer
Decision curve analysis of the nomogram in the training cohort (A), validation cohort (B), and external validation cohort (C). The Y-axis represents a net benefit, and the X-axis represents threshold probability. The green line means no patients died, and the dark green line means all patients died. When the threshold probability is between 25 and 80%, the net benefit of the model exceeds all deaths or none
