Fig. 1From: Pretreatment albumin/fibrinogen ratio as a promising predictor for the survival of advanced non small-cell lung cancer patients undergoing first-line platinum-based chemotherapyThe ROC curve analysis of the AFR for OS. The pretreatment AFR was a potential predictor for OS with an AUC of 0.791, 95%CI of 0.731–0.852, a cut-off value of 8.02, a sensitivity of 65.64% and a specificity of 77.33% (P < 0.001).
