*N=1581 for control group, n=1561 for intervention group. First quartile is least deprived, fourth quartile is most deprived.
†N=1397 for control group, n=1365 for intervention group. Risk categories denote top proportions of site population: very high risk (0.5%), high risk (0.5-5%), moderate risk (5-20%), and low risk (20-100%).
