Long-term impacts of complete revascularization on clinical outcomes in patients with coronary chronic total occlusion.

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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The impact of complete revascularization (CR), achieved through the recanalization of coronary chronic total occlusions (CTOs), on long-term patient outcomes remains uncertain. To evaluate this in patients who achieved CR after CTO-PCI with those who did not due to deferred CTO-PCI, the Asan Medical Center Registry was reviewed to identify coronary artery disease (CAD) patients with CTOs treated between January 2003 and December 2018. Patients were included with single-vessel disease with CTO and with multivessel disease who had undergone revascularization for non-CTO lesions. These subjects were divided into those who achieved CR with CTO-PCI and those who did not due to deferred CTO-PCI. Their outcomes were compared following 1:1 propensity score matching. Of the 2746 enrolled CAD patients with CTOs, 1837 achieved CR with CTO-PCI and 909 did not. Propensity score matching yielded 653 patient pairs. The CR-achieving group had a significantly lower 10-year risk of the primary composite outcome of death, myocardial infarction, stroke, or repeat revascularization (hazard ratio [HR]: 0.57; 95 % confidence interval [CI]: 0.46-0.72; P < 0.001), as well as significantly lower risks of death (HR: 0.66; 95 % CI: 0.51-0.87; P = 0.003) and repeat revascularization (HR: 0.67; 95 % CI: 0.48-0.95; P = 0.023). CR was beneficial in all subgroups, including patients with major cardiovascular risk factors such as older age, hypertension, diabetes, and advanced CAD. Compared with incomplete revascularization, CR may significantly reduce the 10-year incidence of major adverse cardiac events in patients with CTO.
