Determinants of 18-month HIV-1 infection or death (Cox proportional hazard model; reference: ZDV long-term breastfed).

ANRS 1201/1202 Ditrame-Plus and ANRS 049a DITRAME cohorts, Abidjan, Côte d'Ivoire.
*Variables with p<0.25 in the comparison of the three treatment groups (table 2). §Estimated cumulative transmission risk (CTR) of HIV-1 infection at 18-month using Kaplan-Meier estimates. §§Log-rank test; CI: confidence interval; #univariate = unadjusted Cox proportional hazards model; HR: hazard ratio; HRa: adjusted Hazard Ratio; 3TC = lamivudine; sdNVP = single-dose nevirapine during labour; ZDV  = zidovudine. ART = highly active antiretroviral therapy if WHO clinical stage 4 or WHO clinical stage 3 and CD4<350 /mm3 or WHO clinical stage 1/2 and CD4<200/mm3. #in the adjusted analysis, this variable took into account both the treatment duration and the antiretroviral regimen used.
