CI = confidence interval; HTN = hypertension; MACE = major adverse cardiac events; OR = odds ratio.

  • Each factor is based on the final optimal multivariable logistic regression model in which all factors had a p value <0.1 in the univariate model were taken into account. Factors such as age, race, insurance, diabetes mellitus, valvular disease, teaching hospital, transient hypertension, pre-eclampsia status, multiple gestation, postpartum hemorrhage, cesarean delivery, year, and CDM were significantly associated with MACE after adjusting for these factors (all p values < 0.0001).
