Random intercept logistic regression model of good respiratory status (N=56). The effects of Drug A and Placebo are measured with respect to baseline respiratory status.^a

Parameter name	Parameter estimate	P-value	95% CI

Age	−0.073	0.05	[−0.15, 0.0004]
Drug Ab	1.81	0.002	[0.65, 2.98]
Placeboc	0.49	0.39	[−0.63, 1.62]

CI: Confidence interval.

^aThe dichotomous respiratory status was defined as 1 if the subject had a good respiratory status (status 3 or 4), 0 otherwise.

^bThe dichotomous variable was defined as 1 if the respiratory status was obtained under Drug A, or 0 if it was obtained at baseline or under Placebo.

^cThe dichotomous variable was defined as 1 if the respiratory status was obtained under Placebo, or 0 if it was obtained at baseline or under Drug A.
