Multiple linear regression of %FMD (% change in brachial artery diameter after flow-mediated dilation), a measure of endothelial function in the brachial artery

Predictor	β Coefficient	P value
Obese control	−0.43	0.670
Type 2 diabetes	−2.31	0.022
OSA	−2.45	0.015
Baseline brachial artery diameter (mm)	−3.75	0.000

Groups were referenced to the normal-weight controls. Although baseline brachial artery diameter was the major predictor of %FMD, type 2 diabetes and OSA status negatively predicted %FMD as well. For this model, R² = 23.5%.

OSA, obstructive sleep apnea.
