Delayed Partial Protrusion of the Lead After Left Bundle Branch Pacing: The Importance of Programming-A Case Report.
Article in Pacing and clinical electrophysiology : PACE, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Delayed lead perforation into the left ventricular (LV) cavity after left bundle branch area pacing (LBBAP) is less common than in the acute setting and could be associated with severe adverse events. We present the case of a young patient with symptomatic second-degree atrioventricular block who developed partial protrusion of the LBBAP lead into the LV cavity after discharge. While adequate conduction system capture was still seen with bipolar pacing, this potentially serious complication was self-diagnosed by the patient due to the initial ventricular pacing programming in a unipolar setting, which revealed the complete loss of capture.
