  2. Definitions: High cholesterol ≥6.19 mmol/L; Low HDL-C <1.036 mmol/L; High Triglycerides ≥2.26 mmol/L; High Non-HDL-C ≥5.15 mmol/L; High TG/HDL-C ≥2.18; High TC /HDL-C ≥5.97.
  3. *Values are age and multivariate adjusted percentage from pooled logistic regressions including examination cycle to account for correlated observations.
  4. †Adjusted for age, propensity score, and examination cycle.
