Fig. 1

Receiver operating characteristic (ROC) curve analysis performed using pre-operational fibrinogen (FBG) levels to determine the best cutoff point for predicting the survival of gastric cancer patients. a When FBG cutoff value was set > 2.6 g/L, the sensitivity was 81.3 %, the 95 % confidence interval (CI) was 69.5–89.9; the specificity was 27.3 % and the 95 % CI was 24.7–30.1; b When the FBG cutoff value was set ≤ 3.68 g/L, the sensitivity was 78.8 %, the 95 % CI was 74.9–82.4; the specificity was 40.7 % and the 95 % CI was 36.9–44.6
