  3. *Adjusted for Age, Gender, Smoking, Diabetes, Cholesterol/HDL ratio, Vitamin D (serum 25(OH) D).
  4. **Adjusted for Age and Gender.
  5. ***Bold numbers – Statistically significant at 0.05 level.
  6. #Framingham Risk Score - Adjusted for Vitamin D (serum 25 (OH) D) only as this is a composite index of Age, Gender, Smoking, Diabetes, Cholesterol/HDL ratio, Hypertension. The cut off level was arbitrarily set at 15 (mean – 16.3 and median – 12.7).
  7. Pre-migration zone 3 (n = 12) was amalgamated to zone 2 due to its small numbers.
