  1. Notes: CVD = cardiovascular disease, AHC = adult health check, SE = standard error, N = number, HDL = high density lipoprotein, NZGG = New Zealand Guidelines Group.
  2. * Test for difference between findings at the AHC and at review. Means were tested by a paired two-tailed t-test. Proportions were tested using McNemar's test.
  3. † Cigarettes per day (cpd) categories: 1 = 5cpd, 2 = 10cpd, 3 = 15 cpd, 4 = 20+ cpd.
  4. ‡ NZGG risk categories: 4 = 10 to 15% over 5 years, 5 = 15 to 20% over 5 years, 6 = 20 to 25% over 5 years, etc.
  5. § Two-tailed t-test for difference between observed absolute CVD risk at post-AHC review and expected (change in age only) absolute CVD risk at post-AHC review.
