* China National Hypertension Survey Epidemiology Follow-up Study
- †CHD defined as myocardial infarction (ICD-9 410, 412 or ICD-10 I21, I22), angina and other CHD (ICD-9 411, 413 and 414, or IC-10 I20, I23–I25), and a fixed proportion of "ill-defined" cardiovascular disease coded events and deaths.[33] (ICD-9 codes 427.1, 427.4, 427.5, 428, 429.0, 429.1, 429.2, 429.9, 440.9 or ICD-10 I47.2, I49.0, I46, I50, I51.4, I51.5, I51.9, and I70.9). The conservative definition of CHD assumed that very few CHD deaths were misclassified into ill-defined cardiovascular codes, so few of those deaths were counted as CHD deaths.
- ‡The more liberal coding method used the same ICD codes described above, but assumed that a higher proportion of CHD deaths were mis-coded into the "ill-defined" cardiovascular codes, so more deaths assigned these ill-defined codes are counted as CHD deaths.[33]
