Clinical Impact of Lesion Complexity on 2-Year Outcomes After Zotarolimus-Eluting Stents Implantation.

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
Background: The clinical efficacy and safety of second-generation drug-eluting stents in complex percutaneous coronary interventions (PCIs) are not well established. Objectives: The clinical influence of the lesion complexity after PCI with zotarolimus-eluting stents (ZES) was evaluated. Methods: From a prospective multicenter observational study, a total of 926 patients that underwent successful PCIs with ZES were included. Complex PCIs were defined as patients with ≥3 lesions treated, 3 vessels treated, severe calcified lesions, bifurcated lesions with 2 stents implanted, left main disease, chronic total occlusion lesions, and/or diffuse long (total stent length ≥60 mm) lesions and were compared to the noncomplex group. The primary outcome was incidence of target lesion failures at 2 years, defined as a composite of cardiac death, target lesion-myocardial infarctions, and target lesion revascularization. Results: The patients were divided into complex PCI (n = 249) and noncomplex (n = 677) groups. In the complex PCI group, the 2-year risk of a target lesion failure was not significantly higher than in the noncomplex PCI group (4.8% vs 3.7%; adjusted hazard ratio: 1.373; 95% confidence interval: 0.689-2.738; Conclusions: Up to 2 years after a ZES implantation, the clinical outcomes did not differ according to lesion complexity.
