*Fatal CVD was defined as ICD-9 codes 390–459.
†All CVD events included all fatal CVD (ICD-9 codes 390–459) and non-fatal MI and stroke as described above.
‡Fatal myocardial infarction (MI) was defined as ICD-9 codes 410–414. Non-fatal MI was defined as heart attack or coronary thrombosis, in accordance with the WHO diagnostic criteria.
§Fatal stroke was defined as ICD-9 codes 430–438. Non-fatal stroke events included those that caused a neurological deficit for >24 hours.
CHD, coronary heart disease; CVD, stroke/MI; MI, myocardial infarction.
