View larger version (12K): [in a new window]   Figure 1 Scatter diagram showing relationship between corrected TIMI frame count (CTFC) and minimal luminal diameter (MLD) (A) and coronary flow velocity reserve (CFVR) and MLD (B) before intervention. The estimated regression equations are: 1) CTFC = –22.6 ± MLD + 48.9 (p < 0.0001); 2) CFVR = 0.63 ± MLD + 0.88 (p < 0.0001).

The estimated regression equation is: CTFC/MLD = –1.31 CFVR + 10.3 (p = 0.04).
