Receiver operating characteristic (ROC) curve analysis was performed to determine the cutoff value of TIN counts by using the 0, 1 criterion. In the present study, overall survival status had the largest AUC (0.80217), and we selected cutoff value determined by overall survival status. Cutoff value was selected from the point which was closest to both maximum sensitivity and specificity (21.6 counts/microscopic field). Therefore, high and low TIN density was defined as counts ≤ 21 and counts > 21, respectively. (TIF 217 kb
