  1. * Only subjects from the MDC cardiovascular cohort (N = 4995)
  2. ^Continuous variables are expressed as mean values with standard deviation in parenthesis. Differences in mean values were tested using one-way ANOVA
  3. #Skewed continuous values are expressed as median with interquartile range in parenthesis. Differences in median were tested using Kruskal-Wallis ranksum test
  4. ¤ The distribution of subjects across the categorical variables are expressed as frequency (%). The difference in distribution was tested using the chi-square test
  5. ** P-values < 0.05 were considered as statistically significant
