Impact of IRS on birth weight. Shown are birth weights (clear circles) from infants born to mothers with no IRS exposure (n = 134), >0–20 % exposure (n = 90), and >20–43 % exposure (n = 65). Also shown are model adjusted means and 95 % CI (lines and error bars), and P values comparing birth weights between groups, adjusted for gravidity, gestation age study drugs started, wealth category, LAMP at enrolment, and treatment arm
