Percutaneous coronary intervention in unprotected left main coronary artery stenosis: Mid-term outcomes of a single-center observational study.

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
backgroundPercutaneous coronary intervention (PCI) is an appropriate alternative to coronary artery bypass grafting (CABG) for revascularization of unprotected left main coronary artery (ULMCA) disease in patients with low-to-intermediate anatomic complexity or when the patient refuses CABG even after adequate counselling by heart team. We assessed the safety, in-hospital and mid-term outcomes of ULMCA stenting with drug-eluting stents (DES) in Indian patients.
methodsOur study was a retrospective analysis of patients who had undergone ULMCA PCI at a tertiary center, between March 2011 and February 2020. Clinical characteristics, procedural data, and follow-up data were analyzed. The primary outcome was a composite of major adverse cardiovascular and cerebrovascular events (MACCE) during the hospital stay and at follow-up. The median follow-up was 2.8 years (interquartile range: 1.5-4.1 years).
results661 patients (mean age, 63.5 ± 10.9 years) had undergone ULMCA PCI. The mean SYNTAX score was 27.9 ± 10.4 and the mean LVEF was 58.0 ± 11.1%. 3-vessel disease and distal lesions were noted in 54% and 70.6% patients, respectively. The incidence of in-hospital MACCE was 1.8% and the MACCE during follow-up was 11.5% (including 48 [8.4%] cardiac deaths). The overall survival rates after one, three, five, and nine years were 94%, 88%, 84%, and 82%, respectively. The multivariate analysis revealed that age >65 years and high SYNTAX scores were independent predictors of mid to long-term mortality.
conclusionULMCA PCI with DES is safe and has acceptable in-hospital and mid-term outcomes among patients with low-to-intermediate SYNTAX score.
