Trend of white blood cell count across prepregnancy, pregnancy, and postpartum. (a) Displays the median and 95% confidence interval (light blue zone) for white blood cell count in each week. Gestational age was recorded as weeks, representing the corresponding weeks and days (e.g., 37 weeks means 37 to 37^+ 6 weeks). (b) Compared the median white blood cell count between each two adjacent stages. Wilcoxon test was used for the comparison. ns means P > = 0.05 and **** means P < 0.0001
