Original WOSCOPS results and corresponding results using hospitalised WOSCOPS and Record Linkage events.

Original results from the WOSCOPS study (combining definite and suspect coronary events) compared with those omitting non-hospitalised myocardial infarction (MI) and with results based entirely on record linkage. Data shown are numbers and rates (%) of events for each treatment group, p-value and % risk reduction (RR) for the outcomes of coronary heart disease (CHD) death or MI, non fatal MI and CHD death.
