The remaining 264 participants formed the study “Main Group”.Participants who were found on in-laboratory, overnight, PSG to have a Respiratory Disturbance Index (RDI) ≥ 29 events/hr, were then invited to participate in a 12-month duration cardio-vascular risk factor minimisation and CPAP intervention study between 16Participants in this present report also underwent carotid and femoral artery ultrasonography for measurement of intima media thickness. These results have been reported previously [
