<p>Overall, we assessed 625 intervention and 195 non-intervention PHCs. In the initial phase, the composite IPC score improved by 12.5% (95% CI 11.4-13.4) in intervention PHCs compared to 8.5% (95% CI 6.2-10.8) in non-intervention PHCs. Similarly, in phase II, improvement in the IPC composite score was higher in intervention compared to non-intervention PHCs; 34.9% (95% CI 34.0-35.8) versus 13.2% (95% CI: 11.4-15.1) respectively.</p>
