Data are given as number (percentage) for discrete variables and mean (SD) for continuous demographic variables by pregnancy-induced hypertension diagnosis among the 97 women without chronic hypertension in the second-trimester case-control study. P values are based on the χ2 test for discrete variables or the t-test for continuous variables.
CNTL, control; GA, gestational age; PEC, preeclampsia.
