P < 0.05 indicates statistical significance for the differences observed. Continuous variables are presented as mean ± SD and were analyzed using the independent t-test. Categorical variables, such as blood type, were analyzed using the χ² test. WBC: White blood cell; PLT: Platelet; ALT: Alanine aminotransferase; AST: Aspartate aminotransferase; TBIL: Total bilirubin; DBIL: Direct bilirubin; ALB: Albumin; CRE: Creatinine; BUN: Blood urea nitrogen; HGB: Hemoglobin; TP: Total protein; AKP: Alkaline phosphatase; UA: Uric acid; GDM: Gestational diabetes mellitus.
