*Based on age sex structure in England, 1998 in men and women aged 45–84 years. Where estimates did not cover the age ranges used in this paper, the rate in the closest age band to the ones used in this paper was used. | ||||||
†The MSGP4 (4th national morbidity survey in general practice) involved approximately a 1% sample of the population of England and Wales. The number with angina was crudely estimated from the observed prevalence rate applied to the population of 45–84 year olds in England multiplied by 1%.15 | ||||||
