Table 3 Proportion of placenta malaria found to be PCR+/smear-, stratified by gravidity and maternal HIV status

From: Placental malaria among HIV-infected and uninfected women receiving anti-folates in a high transmission area of Uganda

Maternal HIV status Gravidity PCR+/smear- Smear+ p-value
HIV-infected (n = 30) G1 6 (75) 2 (25) 1.00
  G2 6 (67) 3 (33)  
  G3+ 9 (69) 4 (31)  
HIV-uninfected (n = 87) G1 28 (56) 22 (44) .07
  G2 9 (69) 4 (31)  
  G3+ 20 (83) 4 (17)  
  1. Data are number (%) of patients; PCR+/smear -: placental malaria detected by PCR, but not by blood smear, Smear+: placental malaria detected by blood smear; P-value measuring the association between gravidity and PCR+/smear- placental malaria using Fisher's exact test.
