Adjusted Average Annual Mortality Rate Ratios With Multivariable Poisson Regression Modeling Among Enrollees in the Perinatal AIDS Collaborative Transmission Study (PACTS/PACTS-HOPE) (1986–2004)a
| Era | Rate ratio (95% CI) | P |
| No/monotherapy (1986–1990) | 6.6 (2.15–20.00) | .001 |
| Mono-/dual-therapy (1991–1996) | 2.0 (1.00–4.22) | .068 |
| HAART (1997–2004) | 1.0 | … |
Abbreviations: CI, confidence interval; HAART, highly active antiretroviral therapy.
