Findings Four studies met the inclusion criteria. All were conducted in ANC clinics. Increased enrolment of pregnant women in ART was
observed in ANC clinics that had integrated ART (relative risk, RR: 2.09; 95% confidence interval, CI; 1.78–2.46; I
2
: 15%). Increased ART coverage
was also noted in such clinics (RR: 1.37; 95% CI: 1.05–1.79; I
2
: 83%). Sensitivity analyses revealed a trend for the national prevalence of HIV
infection to explain the heterogeneity in the size of the effect of ART integration on ART coverage (P=0.13). Retention in ART was similar
in ANC clinics with and without ART integration.
