Effect of body mass index on initial clinical presentation among patients with pulmonary tuberculosis.

	Univariable analysis	Multivariable analysis
	cOR (95% CI)	aOR (95% CI)
Symptom presence	0.941 (0.929–0.952)	0.942 (0.930–0.954)
AFB smear positivity	0.913 (0.901–0.926)	0.918 (0.905–0.931)
Cavitary disease	0.928 (0.912–0.943)	0.926 (0.910–0.942)
Bilateral disease	0.917 (0.905–0.930)	0.919 (0.907–0.932)

cOR, crude odds ratio; CI, confidence interval; aOR, adjusted odds ratio; Coef, coefficient; AFB, acid-fast bacilli; TB, tuberculosis. The odds ratios for each variable are calculated using logistic regression. Multivariate logistic regression analysis is adjusted for age, sex, current smoking status, heavy alcohol intake, and the presence of underlying comorbidities.
