Multiple regression model predicting plasma oxidative stress (LPO) of COPD subjects

Independent Variable	Plasma LPO (R2= 0.045, F= 5.471, p= 0.021)
	t	B	p
Plasma glutathione (μM)	2.339	0.159	0.021

p < 0.05 significant using Multiple Linear Regression Analysis

Adjusted for Plasma LPO: Fat % and plasma glutathione
