Table 2 Maternal characteristics and outcome parameters (continued)

From: Obstetric and perinatal outcomes in IVF versus ICSI-conceived pregnancies at a tertiary care center - a pilot study

Variable ICSI IVF p-value
n % n %
Hypertension, Preeclampsia 2 4.1 13 4.6 0.99
Premature rupture of membranes, Cervical insufficiency, Premature contractions 2 4.1 64 22.5 0.0016
Number of hospitalization events*    0.0095

  1. Models are adjusted for correlated influence factors.
  2. *unadjusted - should be adjusted for premature rupture of membranes
  3. Cervical insufficiency, and premature contractions, but the model did not converge then.
