  • 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.
