Figure 2. Kaplan-Meier estimates of overall survival and cause-specific survival according to preoperative Hb levels. (a) Overall survival among patients with stage I disease (p<0.001). (b) Cause-specific survival among patients with stage I disease (p=0.321). (c) Overall survival among patients with stage II disease (p=0.001). (d) Cause-specific survival among the patients with stage II disease (p=0.146). (e) Overall survival among patients with stage III disease (p=0.766). (f) Cause-specific survival among patients with stage III disease (p=0.573).
