The factors associated with placental malaria in multivariable analysis, were malaria during pregnancy (adjusted odds ratio: 2.0; IC 95%: [1.2-3.5], moderate anemia (Hb < 11 g/dL)(adjusted odds ratio: 0.4; Interval Confidence 95%: [0.2-0.7], gravidy (adjusted odds ratio: 1.7; IC 95%: [1.1-2.6], Yopougon locality (adjusted odds ratio: 0.5; IC 95%: [0.3-0.9] (Table 3). Here, GSTM1 is linked to malaria.
