  1. a There were two schools with missing parent practice data in the control group at baseline. These schools were included in the baseline analysis for the primary outcome as ‘not met’ they both had two practices and an additional practice would not have enabled them to meet the four practice criteria
  2. b as reported in 12 month paper [17]
