  • * Results reported as weighted means and SEs.

  • Means and P values were calculated from a repeated-measures regression with protease inhibitor use as the sole predictor. By adjusting for correlation between serial measurements of growth, multiple observations on the same child are effectively down-weighted when calculating means, SEs, and P values.
