Receiver operating characteristic (ROC) curves analysis of 14-3-3σ cutoff score in the training set. (A) 14-3-3σ cutoff point for overall survival in the training set. (B) 14-3-3σ cutoff point for progression-free survival in the training set. At each immunohistochemical score, the sensitivity and specificity for the outcome being studied was plotted, thus generating a ROC curve. 14-3-3σ cutoff score for overall survival, progression-free survival was 3.25 and 3.35 respectively.
