Typically, separate guidelines were developed for each risk factor and treatment was recommended when that factor was above a specified level.1 The recommendations were informed mainly by evidence from cohort studies showing increased relative risks of cardiovascular disease in people with raised levels of the risk factor2 and by evidence from randomised controlled trials showing relative benefits from lowering the factor. 3 4
Over the past decade we have witnessed a remarkable change from these
recommendations based on relative risk to ones based on absolute
