A nomogram was drawn using the LASSO-selected variables for logistic modeling.
Notes: (a) A nomogram was created using five factors that were significantly associated. (b) Based on the logistic model, the calibration curve for the training set was derived. (c) The calibration curve of the testing set was drawn using the logistic model. (d) The ROC curve of the testing set was drawn using the logistic model.
