Fig. (5) — Frequency distribution of pressure-derived collateral flow index (CFI, x-axis) measurements in 295 patients with a chronic total occlusion (CTO), showing Gaussian distribution. In this patient population, the target vessel for percutaneous coronary intervention (PCI) was 34.0% in the left anterior descending (LAD), 46.0% in the right coronary artery (RCA) and 19.0% in the right circumflex (RCX). Frequency distribution shown on Y-axis represents absolute numbers. Published with permission from BMJ Publishing Group Ltd. Reference [102].
