a
RR and CI from a modified Poisson regression model utilizing data from all infants in the cohort (N = 8444). Covariates included study center, GA (<25, 25–28, 29+ weeks), BW (401–750, 751–1000, 1001–1250, 1251–1500), boy, race/ethnicity (non-Hispanic black, non-Hispanic white, Hispanic, other), and an infection group indicator (MRSA B/M, MSSA B/M, non-SA B/M, no B/M). RRs and CIs in each BW group were from a model that included the interaction between BW and infection group in addition to the covariates listed. No RRs were significantly different from 1.0.
