↵4-150 1966–67 rates are directly standardised to the age distribution of OXMIS cases.
The 30 day case fatality rate in 1966–67 was compared with the 28 day case fatality rate in 1994–95. The duration of the earlier study was nine months and the population studied was 375 000. Sudden deaths were defined as coronary deaths that occurred before the patient was seen by a doctor.
