Impact of Angiography-Derived Physiological Patterns of CAD and Optimal Hemodynamics Post-PCI on Residual Angina.
Article in JACC. Asia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05117866 (A Multicenter, Single Arm, Open-label Trial of Prasugrel Monotherapy After PCI With the SYNERGY® Stent in Patients With Chronic Coronary Syndrome or Non-ST-elevation Acute Coronary Syndromes), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundFocal stenotic coronary lesions, as defined by the invasive pullback pressure gradient index (PPGI) measured before percutaneous coronary intervention (PCI), are associated with less residual angina than diffuse lesions as assessed by the Seattle Angina Questionnaire (SAQ).
objectivesThis study aims to investigate the interaction between a lesion's baseline functional phenotype (focal vs diffuse) and the physiological success of PCI, as defined by a post-procedural Murray-based angiography-derived flow ratio (μFR) above 0.90 (adequacy of flow [AOF]), in correlation with angina status at 2 years.
methodsThe ASET-Japan study enrolled 203 patients with chronic coronary syndrome. The baseline functional disease pattern and the achievement of AOF (post-PCI μFR > 0.90) were analyzed as potential factors influencing the rate of residual angina at 2 years.
resultsSAQ scores were obtained in 186 patients. The median follow-up duration was 771 days (Q1-Q3: 752-805). AOF was achieved in in 61.3% (114 of 186; 95% CI: 54.1-68.0), with the μFR post-PCI differing significantly by the lesion's baseline phenotype (diffuse 0.92 ± 0.06 vs focal 0.94 ± 0.04; P < 0.001). At 2-year follow-up, patients in the AOF group with preprocedural focal vs diffuse disease had significantly better angina frequency scores (99.2 ± 3.3 vs 94.8 ± 11.7; P = 0.007), and less frequent residual angina (6.7%; 4 of 60; 95% CI: 2.6-16.2 vs 22.0%; 11 of 50; 95% CI: 12.5-34.9; P = 0.040).
conclusionsIn patients who achieve AOF during PCI, the baseline functional phenotype of treated lesions in patients with or without angina at follow-up is significantly different. A global physiological assessment integrating AOF and the baseline functional pattern of disease is potentially useful to accurately predict residual angina post-PCI.
