A Transvenous Pacing Lead's Journey Leading to Perforation and Hematothorax.

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
Recognition of lead-related complications after cardiac implantable electronic device implantation is challenging. An 86-year-old woman with a cardiac resynchronization therapy pacemaker (CRT-P) presented with recurrent nonspecific symptoms, including pulse-synchronous abdominal pain and dyspnea, over 3 emergency department visits. Right ventricular lead perforation went undiagnosed until significant hemothorax developed. A review of electrocardiographic (ECG) and chest X-ray images from earlier visits revealed that lead perforation could have been diagnosed earlier. This case underscores the diagnostic challenges of CIED complications, especially in patients with nonspecific symptoms. Key findings, such as ECG morphology changes and atypical lead position on X-ray, were missed because of limited knowledge of pacemaker-ECG interpretation and inattentional blindness. Lead perforation may occur several weeks after cardiac implantable electronic device implantation. In CRT patients, a predominantly positive stimulated QRS complex in lead V
