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: Mechanical circulatory support may facilitate high-risk percutaneous coronary intervention (PCI). This study aimed to assess the feasibility, safety and effectiveness of high-risk PCI under the support of venoarterial extracorporeal membrane oxygenation (VA-ECMO) combined with intra-aortic balloon pump (IABP). Methods: We enrolled patients who received VA-ECMO plus IABP-assisted PCI procedures at our center from April 2012 to June 2018. Major adverse cardiac events (MACEs) included all-cause death, myocardial infarction, and target vessel revascularization. Results: A total of 10 patients were included, with a mean age of 71 years, EuroSCORE II of 19.9%, and SYNTAX score of 39.8. Procedural success was achieved in nine (90%) patients. The mean duration of ECMO support was 1.5 hours, and 2.6 stents were implanted per patient. Major complications included contrast-induced nephropathy needing hemodialysis in one (10%) patient, significant hemoglobin drop requiring blood transfusion in two (20%) patients, pulmonary infection in one (10%) patient, and local surgical incision infection in one (10%) patient. The accumulative mortality rates for the nine patients with procedural success were 0, 22.2%, and 44.4% at 1, 3, and 5 years follow-up, respectively. However, cardiac death occurred in only one (11.1%) patient. In addition, two patients received repeat PCI or coronary artery bypass grafting within two years following the index procedure. The overall incidence rates of MACEs were 11.1%, 44.4%, and 66.7% at 1, 3, and 5 years follow-up, respectively. Conclusions: VA-ECMO plus IABP-assisted high-risk PCI was feasible in patients with complex coronary disease, with a high procedural success rate and acceptable mid-term clinical outcomes.
