Table 4 Crude and adjusted incident rate ratios (IRR) of low birth weight, maternal anaemia and perinatal mortality by number of detected malaria infection using Poisson regression

From: An analysis of timing and frequency of malaria infection during pregnancy in relation to the risk of low birth weight, anaemia and perinatal mortality in Burkina Faso
