A random\u2010effects model was used for meta\u2010analysis, heterogeneity was assessed using <jats:italic>I<\/jats:italic>\u2010squared statistics, subgroup and sensitivity analysis was performed followed by publication bias assessment.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Of 576 identified studies, 12 met the inclusion criteria, analysing 2320 cases (1572 with uncontrolled high blood glucose [\u22657% HbA1c] and 748 with controlled low blood glucose [&lt;7% HbA1c]). Low certainty evidence shows that patients with uncontrolled high glucose had a 1.91 times higher risk of TB treatment failure (risk ratios [RR]\u2009=\u20091.91, 95% confidence interval [CI] 1.81\u20133.07, <jats:italic>p<\/jats:italic>\u2009=\u20090.008), and a 2.97 times higher risk of sputum positivity at 3\u2009months (RR\u2009=\u20092.97, 95% CI 1.10\u20138.07, <jats:italic>p<\/jats:italic>\u2009=\u20090.03).
