Non-ischemic Painful Intermittent Left Bundle Branch Block With Infra-Hisian Block Treated Successfully With Biventricular Pacemaker: A Case Report and Literature Review.
Article in Cureus, 2022. 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
Non-ischemic painful left bundle branch block (LBBB) is defined as chest pain that occurs simultaneously with the appearance of left bundle branch block and resolves with the disappearance of the left bundle branch block in patients without evidence of myocardial ischemia. The underlying mechanism of this rare clinical occurrence has not been fully understood, but it has been proposed that it results from ventricular dyssynchrony. In this case report, we present a 65-year-old male with non-ischemic chest pain who was found to have intermittent left bundle branch block (ILBBB) with infra-Hisian conduction delay, treated successfully with a biventricular pacemaker. After excluding the presence of angiographic coronary artery disease, an electrophysiology study was conducted to direct the management and investigate other causes of chest pain. The present study highlights the importance of obtaining electrophysiology studies in patients with painful left bundle branch block with no angiographic evidence of coronary artery disease to diagnose this uncommon syndrome.
