Kaplan–Meier survival curves for OS of EOC patients were calculated based on SII, PNI, PLR, and NLR. a:OS of patients in the low SII group was significantly better than that in the high SII group (P < 0.01); b:OS of patients in the low PNI group was significantly worse than that in the high PNI group (P < 0.01); c:OS of patients in the low PLR group was significantly better than that of patients in the high PLR group (P < 0.01); d:OS of patients in the low NLR group was significantly better than that in the high NLR group (P < 0.01)
