Exploration of the LNM-related AS classifier. A Z-score of the top 30 important AS events (top 19 of them were confirmed as important features, the other 11 were shown as red boxes) and other 20 randomly selected ones (in yellow) via the Boruta algorithm. B The mean cross-validation error regarding the number of AS events in the five-round five-fold cross-validation. C The heat map for PSI levels of AS events in the LNM classifier. The data were normalized via the R function scale. D ROC curves in identifying LNM status of LUSC patients with the classifier by the fivefold cross-validation. LNM, lymph node metastasis
