Establishment of a 11-gene model for predicting the LNM of male PTC patients. (a) LASSO coefficient profiles of the 209 msDEGs. (b) Selection of the optimal λ-value through the cross-validation. The best values by minimum(lambda.min, right vertical dotted line) and 1-SE- criteria (lambda.1se, left vertical dotted line) representing the dotted vertical lines. (c) the forest plot showing the results of the univariate Logistic regression analyses. (e~g) The ROC of the training group (AUC = 0.864); The ROC of the testing group (AUC = 0.847); The ROC of the validation group (AUC = 0.812).
