The β values are derived from linear regression models.
*Unadjusted analyses: F2RL3 methylation=intercept + β (previous smoking).
†Adjusted analysis: intercept + β (previous smoking) + β1 (age)+ β2 (passive smoking).
‡Full model: intercept + β (previous smoking) + β1 (age) + β2 (passive smoking) + β3 (education) + β4 (current residence).
§Unadjusted analyses: logistic regression, cardiovascular disease=intercept + β (F2RL3 methylation).
¶Adjusted analysis, logistic regression: intercept + β (F2RL3 methylation) + β1 (age)+ β2 (body mass index).
