PGF and anemia: At enrolment, women with clinical signs of infection (feeling unwell, history of self-reported fever in preceding 24 hours) and anaemia had higher CRP levels, and peripheral malaria infection was associated with increased CRP (P < 0.001), lower sFlt-1 (P = 0.017), and reduced levels of PlGF (P = 0.006) (Supplemental Tables 1, 2).
