Socio-economic status has been associated with cardiovascular-related morbidity and mortality. In this LIPID study (Long term Intervention with Pravastatin in Ischaemic Disease), Socio-economic status was estimated by linking street address at randomisation to median individual income by census collection district in 1991. Baseline clinical information and outcomes over a median of 7.8 years were recorded as part of the study. Socio-economic differences in coronary heart disease risk factors, symptoms, interventions and mortality were assessed. Proportional Hazard models were used to assess the influence of socio-economic differences on outcomes, in which two methods of measuring were considered, one by absolute change, another by proportional change. Discussion will be given to compare these two methods.
