Association between loneliness and incident atrial fibrillation across different genetic predisposition: findings from the UK Biobank.
Article in European journal of medical research, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundLoneliness has garnered significant attention globally, with extensive exploration of its association with cardiovascular disease. However, a notable research gap persists concerning loneliness and its potential link to atrial fibrillation (AF).
methodsThis prospective cohort study utilized data from the UK Biobank (UKB), encompassing 441,056 participants. Loneliness was assessed through self-reported questionnaires gauging feelings of isolation and willingness to confide. AF diagnoses were ascertained using hospitalization records and cause-of-death registry data. The association between loneliness and AF risk was analyzed through multivariable Cox proportional hazard models.
resultsOver a median follow-up period of 13.9 years, 25,386 AF cases were identified. In comparison to individuals without reported loneliness, those in the loneliness group exhibited a significantly higher risk of AF (loneliness vs. non-loneliness: hazard ratio [HR]: 1.11, 95% confidence interval [CI] 1.07-1.16). Subgroup analysis revealed that the association between loneliness and increased AF risk was significant solely in individuals without heart valve disease (HR: 1.12, 95% CI 1.07-1.16). Additionally, significant associations between loneliness and heightened AF risk were noted across strata of genetic susceptibility to AF, with no observable impact on these associations by genetic susceptibility (P for interaction = 0.070).
conclusionsThis study establishes a robust association between loneliness and an elevated long-term risk of AF. Notably, this association is particularly pronounced in individuals without valvular disease and does not appear to be influenced by genetic predisposition to AF.
