Bivariate and Multivariate Associations Between Receipt of IPTp-SP and Pregnancy Outcomes

	Overall	Suboptimal IPTp	Full IPTp	P Value (Unadjusted)	P Value (Adjusted)a
Maternal parasite density, parasites/μL median (IQR)	526 (60–3495)	780 (105–8370)	226 (49–2118)	.014	.349
Placental parasite density, parasites/μL median (IQR)	1069 (73–9185)	4898 (300–13 800)	168 (52–1072)	<.001	.659

P values determined by linear regression. Parasite densities were natural log-transformed prior to inclusion in regression models.

Abbreviations: IPTp, intermittent preventive therapy with antimalarials during pregnancy; IQR, interquartile range; SP, sulfadoxine-pyrimethamine.

^a Adjusted for gravidity, human immunodeficiency virus infection, delivery year, and Plasmodium falciparum dhfr-dhps haplotype.
