Subgrouping of study populations. (A) The proportions of the study population in terms of tertiles of the classic SYNTAX score (SS) and the functional SS (FSS). A total of 23.9% of patients in the high-SS tertile moved to the intermediate-FSS tertile and 4.4% to the low-FSS tertile. Further, 27.0% of patients in the intermediate-SS tertile moved to the low-FSS tertile. (B) The major adverse cardiac event (MACE) rates to 5 years. The difference in MACE frequency was greater between the low- and intermediate-risk FSS groups, and the high-risk SS group, than that between the low- and intermediate-risk SS groups, and the high-risk SS group.
