Fig. 5From: Development of a nomogram based on the clinicopathological and CT features to predict the survival of primary pulmonary lymphoepithelial carcinoma patientsCalibration curves for 3, 5year DFS (a) of nomogram predictions; Decision curve analysis of nomogram for 3year DFS (b) and 5year DFS (c) of PLEC patients. The red line is the net benefit of a strategy of treating all people; the brown line is the net benefit of treating no people. The yaxis indicates the overall net benefit, which is calculated by summing the benefits (true-positive results) and subtracting the harms (false-positive results), weighting the latter by a factor related to the relative harm of undetected cancer compared with the harm of unnecessary treatmentBack to article page
