*All models were adjusted for gravidity, use of a net/ITN, severe anaemia at enrolment, fever at enrolment and socioeconomic status.
†The total number of babies for each outcome varies due to missing values. Hb was only measured at delivery.
‡Gestational age<37 weeks.
§Spontaneous expulsion of fetus before 24 weeks of gestation.
Hb, haemoglobin; IST, intermittent screening and treatment; ITN, insecticide-treated bed net; PCD, passive case detection; RDT, rapid diagnostic test.
