Sensitivity analysis of the effect of body mass index on mortality among 9,162 patients with isoniazid- and rifampicin-susceptible pulmonary tuberculosis.

Mortality	Univariable analysis	Multivariable analysis	BMI *Sex		Male	Female
	cOR (95% CI)	aOR (95% CI)	Coef	P- value	aOR (95% CI)	aOR (95% CI)
All cause of death	0.889 (0.871–0.907)	0.894 (0.875–0.912)	0.038	0.075	0.880 (0.858–0.904)	0.918 (0.887–0.949)
TB-related death	0.864 (0.829–0.899)	0.882 (0.847–0.918)	0.042	0.305	0.864 (0.819–0.911)	0.909 (0.855–0.967)
Non-TB-related death	0.904 (0.884–0.925)	0.908 (0.888–0.929)	0.035	0.141	0.897 (0.871–0.923)	0.930 (0.896–0.966)

BMI, body mass index; cOR, crude odds ratio; CI, confidence interval; aOR, adjusted odds ratio; Coef, coefficient; AFB, acid-fast bacilli; TB, tuberculosis. The odds ratios for each outcome are calculated using logistic regression. Multivariable analysis is adjusted for age, sex, current smoking status, heavy alcohol intake, and presence of underlying comorbidities. BMI is set as a continuous variable.
