a
Discrete variables expressed as n(column %) and continuous variables as median (IQR);
b
“No TB” includes TB contacts and healthy controls;
c
Statistical differences established by Chi-square of Fisher's exact for categorical or Wilcoxon rank sum test for continuous variables, with P values in bold highlight significant and borderline significant results;
d
n=29 for “DM only” groups; Glycemic index = HbA1c x Years with DM; BMI, Body-mass index; Note: Healthy controls alone are not shown given no significant differences with TB contacts
