Data are n or n (%), unless otherwise indicated. Unless otherwise indicated, relative risks (RRs) with corresponding 95% CIs and p values were calculated from generalised linear models accounting for the cluster-level variance and adjusted for randomisation strata.

^*Calculated from a t test (cluster-level, 62 degrees of freedom [101 clusters–37 strata–2 treatment groups]).
