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
backgroundIntracardiac masses traditionally require surgical resection, but transcatheter techniques offer a less invasive alternative. CASE SUMMARY: A 57-year-old woman with rheumatic heart disease and severe mitral stenosis was evaluated for percutaneous mitral commissurotomy. Imaging revealed a mobile right atrial mass near the inferior vena cava, posing a risk for embolization. Given the need for mass removal before the procedure, we performed the QATAR technique using the Penumbra Lightning 16 system, a loop snare, and electrocautery. The mass was successfully extracted without complications. DISCUSSION: This case highlights the feasibility of a novel transcatheter approach for intracardiac mass removal, reducing the need for open surgery. The QATAR procedure integrates electrosurgery with catheter-based extraction, expanding therapeutic options for high-risk patients. TAKE-HOME MESSAGES: We aim to highlight a novel transcatheter technique combining electrosurgery and catheter-based therapies to remove intracardiac tumors. The QATAR procedure is a safe and effective technique for intracardiac mass removal, offering a minimally invasive alternative to surgery.
