Data are number (%). Terminations of pregnancy (n=103) were excluded from this table. PPROM=preterm prelabour rupture of membranes.
*Gestational age at PPROM 16+0-22+6 weeks+days.
†P value was 0.30 compares latency between PPROM and birth by gestational age category at PPROM, calculated with χ2 test.
PPROM, preterm prelabour rupture of membranes.
