Figure 5 Sensitivity and Specificity of MPR to Detect CAD With  50% DS
Graphics showing sensitivity, specificity, and predictive values of MPR using a cutoff of 2.04 as determined by receiver-operating curve analysis to detect CAD with 50% DS. Heterogeneity of variance in MPR levels correlated with percentage diameter stenosis (DS) was evaluated by the Welch approximation for unequal variances from the independent-sample t test (p = <0.0001). Abbreviations as in Figure 4.
