Figure 1 Additional analysis 2. Incidence rate and adjusted hazard ratios for the composite outcome of heart failure, cardiomyopathy, or cardiac arrhythmia starting 1 day after the index delivery discharge date, in association with exposure to prolonged first stage of labour. Data are stratified according to parity, previous Cesarean delivery, as well as current spontaneous vaginal delivery, induction of labour, and forceps or vacuum assisted vaginal delivery. CI, confidence interval. ∗Adjusted for maternal age, parity, obstructed labour, or fetal malposition, preeclampsia, income quintile, rural residence, preterm birth, and infant birthweight—each at the time of a given delivery; time-varying drug/tobacco use, obesity, diabetes mellitus, chronic hypertension, kidney disease, dyslipidemia—each diagnosed before or at the time of a given delivery; as well as newly diagnosed coronary artery disease or congenital heart disease arising at least 1 day after the index delivery discharge date.
