Recent uptake of intermittent preventive treatment during pregnancy with sulfadoxine–pyrimethamine is associated with increased prevalence of Pfdhfr mutations in Bobo-Dioulasso, Burkina Faso

Table 4 Predictors of parasite density and maternal haemoglobin level

Maternal outcome	Adjusted coefficient (95% CI)	P value
Log10 of parasite density (parasite/μl)
Primigravida	0.35 (0.08 to 0.62)^a	0.011
Early IPTp-SP	0.30 (−0.01 to 0.60)^a	0.05
Haemoglobin level (g/dl)
Living in Kua	0.90 (0.24 to 1.55)^b	0.008

^b Multivariable analysis using linear regression adjusted for age, gravidity, education, use of IPTp-SP, parasite density, and Pfdhfr intermediate-to-high resistance
