Associations of chronic pain and genetic risks with incident atrial fibrillation: a prospective cohort study.
Article in BMC cardiovascular disorders, 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
backgroundCurrent knowledge on whether chronic pain contributes to atrial fibrillation (AF) risk, especially under varying genetic susceptibilities, is limited. This study aimed to explore the association between chronic pain and AF risk and assess the combined impact of chronic pain and genetic susceptibility to AF, as defined by polygenic risk scores (PRS), in the UK Biobank cohort.
methodsWe analyzed data from 290,345 UK Biobank participants who were initially AF-free. Based on pain duration and location, participants were categorized into four groups: no pain, short-term pain, chronic localized pain, and chronic widespread pain (CWP). Genetic susceptibility to AF was quantified using PRS, categorizing individuals into low, intermediate, and high genetic risk groups. Cox proportional hazard regression analyses were conducted to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for assessing the risk of AF about chronic pain and genetic susceptibility.
resultsOver a median follow-up of 14.2 years, 19,998 participants (6.9%) developed AF. All pain categories were associated with a statistically significant increased risk of AF compared with the no pain category. Both chronic pain and higher PRS were independently associated with incident AF. Joint analyses revealed that, in the high genetic risk group, individuals with chronic localized pain and CWP had HRs of 3.52 (95% CI: 3.25-3.81) and 3.32 (95% CI: 2.71-4.08), respectively, compared to the low genetic risk and no pain group.
conclusionsChronic pain and PRS were independently associated with an increased risk of AF, and individuals with combined exposures had the highest risk.
