The results for the input parameters for the model were:
maternal HIV seroprevalence, 1.5% (range: 0.4% - 3%);
mothers accept rapid test, 85% (range: 60% - 100%);
sensitivity of rapid test, 99% (range: 90% - 99.9%);
specificity of rapid test, 99% (range: 98% - 99.9%);
sensitivity of western blot, 97% (no range);
specificity of western blot, 99.4% (no range);
intrapartum hospitalisation greater than 4 hours, 45% (range: 30% - 60%);
accept zidovudine if HIV seropositive, 100% (range: 70% - 100%);
intrapartum HIV transmission without zidovudine treatment, 25.5% (no range);
intrapartum HIV transmission after intrapartum and neonatal zidovudine, 16.5% (range: 8.3% - 25.5%);
intrapartum HIV transmission after neonatal zidovudine only, 25.5% (range: 8.3% - 25.5%);
HIV transmission rate caused by breast-feeding, 12% (range: 7% - 22%);
prevalence of breast feeding, 18% (range: 5% - 30%);
prevalence of breast-feeding if known HIV seropositive, 2% (range: 0% - 5%).
