a trend toward significanceP = 0.063
These results are depicted in the correlation matrix shown in Table 2 . Multivariate Analysis of Covariance The multivariate analysis demonstrated that stress MBF is an independent significant predictor ( P < .001, η 2 = 0.111) of the ventricular function (LVEF, MFR/3, and E), while MPR showed only a trend toward significance ( P = 0.063).
