Study participant flow and testing results.
The chart shows the total number of pregnant women recruited during antenatal care visits and at delivery, the number of peripheral and placental blood samples collected, as well as the overall number of malaria infections detected by each test. *Discrepant results when compared with the reference test ANC (antenatal care); Pos. (positive); Neg. (negative); LM (light microscopy); Pf (P. falciparum); Pv (P. vivax); RDT (rapid diagnostic test); HS-RDT (highly sensitive rapid diagnostic test); nPCR (nested polymerase chain reaction).
