Figure 4 Stents implanted (units) in quantitative flow ratio (QFR)-guided and angiography-guided percutaneous coronary intervention (PCI) groups during second-stage stenting procedure. This bar chart illustrates the statistically significant difference in the number of stents implanted between the QFR-guided and angiography-guided PCI groups during the second-stage stenting procedure, showing that the QFR method was associated with fewer stents per procedure (1.69±1.0 vs 2.26±0.14). χ2=10.971; lls=4; P=0.027; *, ** P<0.05, based on the χ2 independence test.
