Data are expressed as mean ± standard deviation or median (interquartile range).

CA‐125, carbohydrate antigen‐125; dNLR, derived neutrophil‐to‐lymphocyte ratio; Hb, hemoglobin; WBC, white blood cell count.

^* P < 0.05, ovarian cancer group vs benign ovarian disease group.

^** P < 0.05, ovarian cancer group vs healthy control group.

^*** P < 0.05, benign ovarian disease group vs healthy control group.
