Figure 4: Kaplan–Meier curves. (a) Disease-free survival is compared between Stage I, II and III oral cancer. Estimated DFS was 82.2% (88%, 77.8% and 50% for Stage I, II and III, respectively, Log-Rank P= 0.1661). (b) Overall survival is compared between Stage I, II and III oral cancer. OS was 91.1% (96%, 88.9% and 50% for Stage I, II and III, respectively, Log-Rank P= 0.0002)
