Abbreviations: BMI, body mass index; CAD, coronary artery disease; IQR, interquartile range; LTBI, latent tuberculosis infection.
aData represent No. (%) of study participants unless otherwise specified.
bOne of the 215 study participants had an indeterminate quantiFERON-TB test result; therefore, 214 participants were included in this analysis.
cThe χ2 test was used for categorical variables, and the Mann-Whitney test for numeric variables.
