Continuous variables were expressed as the mean with standard deviation (SD) and were tested for normality distribution with the Kolmogorov–Smirnov test. Independent t-tests were performed for normally distributed variables, and Mann–Whitney U-tests were performed otherwise. Categorical variables are presented as frequencies with percentages and were analyzed by the chi-square test or Fisher’s exact test, as appropriate.
NP Normal Pregnancy, PE Preeclampsia, BMI Body Mass Index, SBP Systolic Blood Pressure, DBP Diastolic Blood Pressure, IQR Interquartile Range, SD Standard Deviation.
