skewed, as median (interquartile range, Q1-Q3) for the continuous variables, and
as a percentage for categorical variables. Differences between groups were
examined with Student’s t-test or Mann–Whitney’s test. The
relationships between indicators of IR and other factors were determined using
univariable linear regression and multivariable linear regression. Pearson’s r
and standardized B were calculated for the correlation between IR indices and
quantitative variables (such as developmental features of the fetus from
ultrasound findings, blood pressure, maternal weight, total cholesterol,
triglycerides, HDL-C, LDL-C, and hemoglobin) and dichotomous variables (family
history of diabetes, acanthosis nigricans, and lipid disorders). A
P-value < .05 was considered statistically significant.
Data were processed using SPSS software version 26 (64-bit) for Window (SPSS
Inc, Chicago, IL).
