 Effect of OSS in each group 1.21 (0.61, 2.38), 0.478 0.90 (0.63, 1.28), 0.443
  1. **Denotes that the effect of OSS was significant at the .01 level and *Denotes that the effect of OSS was significant at the .05 level
  2. The 99% confidence intervals (CI) are based on the .01 level of significance
  3. Abbreviations: aRR adjusted relative risk, aRRR adjusted ratio of relative risks, IMID Integrated Management of Infectious Disease, OSS On-site support, MLP Mid-level practitioners, RR Relative Risk measured the comparisons in pre/post change from Time 0 to Time 1; RRR Ratio of Relative Risk Measured the effect of OSS in each subgroup
  4. Estimates were adjusted for: whether the facility received the on-site intervention from Baylor International Pediatric AIDS Initiative or not, facility was implementing continuous quality improvement prior to IDCAP trial, level of health facility (small hospital or health center IV), facility ownership (public or private-not-for profit) and data entry assistant on-site
