Serum RSV-Neutralizing Antibody Levels for Mothers and Newborns According to Maternal HIV Infection

RSV Antibody Measurement	Maternal HIV Status		P	P adj
	HIV Infected (n = 154)	HIV Uninfected (n = 162)
Maternal GMT (95% CI)	3100 (2675–3591)	2983 (2623-3392)	.70	.09
Placental transfer ratio (95% CI)	1.02 (0.93–1.12)	1.15 (1.03-1.27)	.11	.02
Newborn GMT (95% CI)	2657 (2251–3136)	2911 (2543-3331)	.40	.002

Abbreviations: CI, confidence interval; GMT, geometric mean titer; HIV, human immunodeficiency virus; RSV, respiratory syncytial virus.

P values were estimated from Student t tests.

P _adj values were estimated from multivariable linear regression models adjusted for enrollment month and maternal age.
