aMean difference = mean in group B clusters – mean in group A clusters. Negative mean differences indicate higher values on average in group A (early intervention) clusters.

bPaired t-test.

cFor this variable one cluster provided no data and so this cluster and its pair have been excluded (9 degrees of freedom).
