a
Mean TMAO was 5.8 µmol/L (SD 5.6) for subjects above the median and 2.0 µmol/L (SD 0.6) for subjects below the median.
b
Data shown is mean and SD or number and percent. P-values are from independent samples t-tests (two-sided), from Chi square tests for categorical variables, or from Fisher’s Exact test for current smoking.
