Comparison of obstetric, maternal, and neonatal outcomes between preterm prelabor rupture of membranes at 34 + 0–36 + 6 weeks and term prelabor rupture of membranes at ≥ 37 weeks

To compare preterm prelabor rupture of membranes (PPROM) at 34 + 0–36 + 6 weeks with term prelabor rupture of membranes at ≥ 37 weeks in terms of obstetric outcomes, maternal morbidity, and short-term neonatal outcomes. This retrospective cohort study included 646 singleton pregnancies diagnosed with PROM at 34 + 0 weeks or later in a tertiary care center between January 1, 2018 and July 30, 2025. Cases were grouped as PPROM at 34 + 0–36 + 6 weeks ( n = 334) and term PROM at ≥ 37 weeks ( n = 312
