ROC curves of NLR (a), PLR (b), LMR (c), and SII (d) on RFS and OS. a The AUC for RFS and OS were 0.569 (95%CI = 0.459–0.679, P = 0.250) and 0.565 (95%CI = 0.461–0.669, P = 0.239). b The AUC for RFS and OS were 0.592 (95%CI = 0.477–0.707, P = 0.125) and 0.568 (95%CI = 0.460–0.675, P = 0.222). c The AUC for RFS and OS were 0.561 (95%CI = 0.447–0.674, P = 0.310) and 0.597 (95%CI = 0.493–0.701, P = 0.079). d The AUC for RFS and OS were 0.626 (95%CI = 0.517–0.736, P = 0.035) and 0.617 (95%CI = 0.515–0.719, P = 0.034).
