Correlation of sputum IL-10 transcript with fasting blood glucose and HbA1c levels. IL-10 transcript levels in sputum samples from TB and TB-DM patients combined (n = 22) were correlated with fasting blood glucose at (a) baseline and after (b) 1 month and (c) 2 months, and HbA1c levels at (d) baseline and after (e) 1 month and (f) 2 months of anti-TB treatment. Data is presented as median and the correlation was calculated using Spearman’s correlation test. *p < 0.05 was considered significant
