Multiple linear regression models.

		Outcomes
		PaO2 at rest	6MWT	PCS	IWQOL
		(mmHg)	(meters)
Predictors	Waist circumference (cm)	𝛽=−0.23 *; 𝑃=0.02	𝛽=0.9; 𝑃=0.5	𝛽=−0.15; 𝑃=0.14	𝛽=−0.04; 𝑃=0.86
	PaO2 at rest (mmHg)		𝛽=2.27	𝛽=−0.19	𝛽=−0.01
			𝑃=0.12	𝑃=0.25	𝑃=0.99
	6MWT (meters)			𝛽=0.05 *; 𝑃=0.00	𝛽=−0.01; 𝑃=0.71
	PCS				𝛽=1.07 *; 𝑃=0.002
	MCS				𝛽=0.82 *; 𝑃=0.03

The effect of the predictors is estimated in four regression models for four different outcomes. *Significant at <0.05.
