Adding Insult to Injury: When Atrial Fibrillation Encounters Left Bundle Branch Block.
Article in Reviews in cardiovascular medicine, 2024. 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
Background: It is not uncommon that atrial fibrillation (AF) coexists with left bundle branch block (LBBB). Whether LBBB is an independent predictor of poor prognosis in AF patients remains undetermined. This study aims to investigate the impact of LBBB on the AF-related outcomes in non-valvular AF patients. Methods: The clinical data of AF patients were collected from the Medical Information Mart for Intensive Care-III (MIMIC-III) database. The frequencies of acute arterial embolism events (AEE) and in-hospital cardiac death were compared between the non-LBBB and LBBB groups. And, their 1-year mortality was assessed through a survival analysis model. Additionally, the two groups were matched in a 1:2 ratio by a propensity score matching (PSM) method according to the CHA Results: 5051 patients diagnosed with non-valvular AF without apparent structural heart disease were enrolled in this study, among them, there were 65 with LBBB which had more AEE (13.8% vs 6.8%, Conclusions: The LBBB was an independent risk factor of AEE and related to in-hospital cardiac death and 1-year all-cause mortality in this non-valvular AF cohort from MIMIC-III.
