*P value < 0.05; Categorical variables were compared by using the chi-square test. Continues variables were compared by using the Student t test or Mann-Whitney U test;
TCHO, total cholesterol; TG, triglyceride; HDLC, high density lipoprotein; LDLC, low density lipoprotein; CA125, carcinoma antigen 125; CEA, carcinoembryonic antigen.
