Note: value labeled is the unstandardized regression coefficient from mixed model. Ischemia was scored as ischemia = 1 and no-ischemia = 2. Dash indicates that the variable was not included in the model. Model 1 refers to main effect of FMD and ischemia on peak VO2, Model 2 refers to their interaction effects on peak VO2, Model 3 represents the main effects of GTNMD and ischemia on peak VO2, and Model 4 represents their interaction effects on peak VO2.
