*Variables retained in the reduced model using the likelihood ratio test are: age, timing ANC initiation, pregnancy status, hemoglobin, parity, and recent pregnancy complications. Recent pregnancy complications include antepartum hemorrhage, PROM (premature rupture of membrane), PIH (pregnancy-induced hypertension), gestational diabetic mellitus, and threatened abortion.
