Multiple logistic regression analyses were performed to determine the risk factors associated with default among those with pulmonary tuberculosis. The important risk factors associated with default included male sex (odds ratio [OR] = 1.3; 95% confidence interval [CI], 1.2–1.7), low educational level (OR = 1.9; 95% CI, 1.6–4.3), non-Kuwaiti nations (OR = 2.4; 95% CI, 1.9–6.4), a history of default (OR = 1.6; 95% CI, 1.1–2.9), diabetes mellitus (OR = 1.6; 95% CI, 1.8–4.4), liver disease (OR = 1.4; 95% CI, 1.2–3.3), and lung cancer (OR = 1.3; 95% CI, 1.1–2.7).
