Scatter plots showing correlation between translesional pressure gradient and lesion geometry. (A) Pd/Pa vs. diameter stenosis; (B) Pd/Pa vs. minimal lumen diameter; (C) Pd/Pa vs. lesion length; (D) Pa-Pd vs. diameter stenosis; (E) Pa-Pd vs. minimal lumen diameter; (F) Pa-Pd vs. lesion length. Pd indicates distal pressure of stenosis; and Pa indicates proximal pressure of stenosis. ※ indicates Spearman test for non-normally distributed variables; and ^† indicates Pearson test for normally distributed continuous variables.
