Sessions of acupuncture and nutritional therapy evaluation for atrial fibrillation (Santé-AF): a randomised feasibility study.
Article in Pilot and feasibility studies, 2025. 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
backgroundAtrial fibrillation is a common cardiac arrhythmia, associated with debilitating symptoms and a decrease in health-related quality of life. Current treatments for atrial fibrillation may not provide symptomatic relief and are associated with risks and adverse responses. Large-scale trials are justified to investigate whether complementary therapies may improve symptoms and/or health-related quality of life in atrial fibrillation. To reduce the uncertainty of a future trial, a feasibility study was carried out. DESIGN AND
methodsA three-arm, parallel-group, pragmatic randomised controlled feasibility study recruited 30 participants with paroxysmal AF aged 45-70 from NHS primary care, randomising to Group A (acupuncture + usual care), Group B (nutritional therapy + usual care) or Group C (usual care alone) using a 2:2:1 allocation ratio in favour of the interventions. Interventions were delivered by private practitioners. Seven feasibility objectives were investigated, including participants' willingness to take part, appropriateness of eligibility criteria, participant retention and acceptability of interventions and study assessments. Additional exploratory feasibility objectives were investigated, including the effect of the COVID-19 pandemic and the safety of interventions. Data was analysed using descriptive statistics and reflexive thematic analysis, and the study used a sequential convergent mixed methods design to understand whether, and why, objectives were feasible and to make recommendations for a future trial.
resultsFive feasibility objectives' progression criteria were met, one did not meet its progression threshold and one was abandoned as infeasible to analyse but did not affect feasibility. Recommendations for a future trial include changes in eligibility criteria to reflect real-world populations and changes to assessment methods to reduce participant burden. Uncertainty remains around the effect on the feasibility of reversion to pre-COVID therapy and study assessment delivery, including a recommended longer follow-up.
conclusionA future large-scale trial was found to be feasible with adjustments, but some uncertainty remains.
