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: Atrial lead dislodgment is not uncommon after permanent pacemaker implantation, especially in patients with atrial anatomic abnormity. Unique electrocardiography manifestation might give clues for promptly diagnosis. In patients with reconstructed right atrium, optimal pacing strategies and lead stability remain challenging. Case presentation: A 44-year-old woman developed symptomatic sinus node dysfunction after right atrial tumor resection and reconstruction. A dual-chamber pacemaker was implanted, resulting in symptom resolution. At routine follow-up, electrocardiography showed ventricle was intermittently captured by one initial pacing artifact which was immediately followed by another pacing artifact at a fixed interval of 110-ms, consistent with ventricular safety pacing. Device interrogation revealed normal ventricular lead parameters but loss of atrial capture. Imaging confirmed atrial lead dislodgement into the right ventricle. The atrial lead was subsequently extracted and the device was reprogrammed to VVI mode. After 3 months follow-up, the patient remained asymptomatic and was with normal cardiac function. Conclusion: This case highlights the importance of diagnostic role of electrocardiography to detect lead dislodgement. In patents with surgically altered right atrium, individualized pacing strategies, such as single-chamber ventricular pacing, may be appropriate. Novel atrial pacing lead with fix helix or leadless pacing might do some help to reduce the risk of dislodgement.
