Table 2. HIV prevalence among those in-school and out of school, and crude and adjusted odds ratios for the association between current school attendance and HIV prevalence in individual surveys.
Data were weighted to account for individual sampling probabilities. S1 Table presents the adjusted odds ratios and associated confidence intervals for all covariates included in the final adjusted model.
| Survey | HIV prevalence for those currently in education % (n/N) |
HIV prevalence for those not currently in education % (n/N) |
Crude odds ratio (95% Confidence interval) |
Adjusted odds ratio 1 (95% Confidence interval) |
