<p>Footnote: BS: bloodsmear. CI: confidence interval. CRP: C-reactive protein. EP: Erthyrocyte protoporphyrin. Hb: hemoglobin. sTfR: Soluble transferrin receptor. *Adjusted odds ratios used: Kabyemela 2008: odds ratio adjusted for gravidity. Senga 2011: odds ratio adjusted for gravidity, age, and blood group. Placental histology in Senga 2011: active infection defined by acute or chronic infection (parasites alone, or parasites in the presence of haemozoin). No placental infection defined by the absence of parasites and haemozoin. ** Ferritin 30/CRP 8.3: Ferritin <30 ng/mL & CRP< = 8.2 ng/mL or ferritin <70 ng/mL & CRP>8.2 ng/mL. The weight for each study is indicated as a grey block around the risk estimate.
