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: Extra-vascular implantable cardioverter defibrillator (EV-ICD) is an emerging technique for ICD implantation with substernal lead placement. The system avoids the vasculature and can deliver anti-tachycardia and pause prevention pacing, with a generator size smaller than the existing subcutaneous device. While this device is now widely available, little is known about potential complications that may follow its implantation in real life context. Case summary: We report the case of a 46-year-old male with a history of non-ischaemic dilated cardiomyopathy, severely reduced left ventricular ejection fraction, and intravenous drug use who underwent EV-ICD implantation for primary prevention of sudden cardiac death. The device implantation was uncomplicated with initial satisfactory device parameters and fluoroscopic position. However, post-implant chest radiograph demonstrated lead dislodgement. Despite meticulous assessment on post-implantation CT, the exact position of the dislocated lead couldn't be determined with certainty. Lead revision was performed at 1 month following implantation, and fluoroscopic assessment at this time revealed lead movement synchronous with respiration, raising suspicion that the lead was intra-pleural. A sheath was repositioned over the dislocated lead and contrast injected. Contrast dispersion confirmed the intra-pleural positioning of the lead and was subsequently used as landmark for the appropriate substernal retunnelling of the lead. At most recent follow-up, lead position on chest radiograph and device parameters were satisfactory. Discussion: Extra-vascular implantable cardioverter defibrillator lead placement and dislodgement within the pleural space can follow apparently uncomplicated implantation. Both cine-imaging and contrast injection can be used for accurate assessment of the lead position relative to the pleura and help successful reimplantation.
