¹Two covariates were included in each multivariate model: HRM score measured at 6–8 weeks of age (binary, ≤75^th percentile vs. >75^th percentile) and HIV viral load measured at 14 weeks of age (log₁₀ scale). N: number of infants included in the model; CI: confidence intervals

²Hazard ratio, 95% CI, and P value for HRM score at 6–8 weeks of age.

³Hazard ratio, 95% CI, and P value for HIV viral load at 14 weeks of age (log₁₀ scale).
