  1. Bold fonts indicate the significant differences
  2. #P-values are computed based on independent t-tests for baseline measurements
  3. ##Model 1 P-values and MD (95% CI) are computed based on Analysis of Covariance for measurements taken on post, 1 and 6 months after intervention, after adjusting for baseline measurements
  4. $Model 2 P-values are computed based on Analysis of Covariance for measurements taken on post, 1 and 6 months after intervention, after adjusting for baseline measurements and potential confounders including the age, occupation, family dimension and the education level
