95% Confidence intervals for difference in proportion between intervention groups and control group (values are percentages): any immunisation—intervention A −2.3 (−13.0 to 8.4), intervention B −6.0 (−16.4 to 4.4); primary course—intervention A 2.2 (−12.9 to 17.3), intervention B −1.5 (−15.9 to 12.9); measles, mumps, and rubella—intervention A −6.5 (−21.7 to 8.7), intervention B −9.8 (−24.7 to 5.1).
