In reply: The Health Improvement and Prevention Study (HIPS) and the Greater Green Triangle study are not comparable. HIPS was a cluster randomised controlled trial of a pragmatic intervention that was delivered by general practitioners (through Divisions of General Practice) and was analysed on an intention-to-treat (ITT) basis.1 The Greater Green Triangle study was a pre–post study of patients recruited in GP waiting rooms who completed a program delivered by study staff (ie, it was not analysed on an ITT basis).2
