Logistic multivariate regression models evaluating the association of BMI and leptin with maximum respiratory support.

	Dependent variable: use of VM/HFNC vs NIMV
Predictive variables	OR	95% CI	p value
Age	1.10	(1.01–1.23)	0.048
Sex (M)	3.38	(0.51–31.85)	0.237
BMI	1.39	(1.09–1.96)	0.023
Leptin	1.00	(0.99–1.00)	0.491

BMI is for body mass index; NIMV is for noninvasive mechanical ventilation; VM/HFNC is for Venturi mask/high-flow nasal cannula (VM/HFNC); OR is for odds ratio; CI is for confidence interval.
