Data from a UK-based multicentre randomised feasibility study investigating the management of post-traumatic benign paroxysmal positional vertigo: mixed-methods analyses.
Trial report in BMJ open, 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
objectivesTraumatic brain injury commonly causes dizziness and balance problems. Benign paroxysmal positional vertigo (BPPV) is the most frequent cause of inner-ear related post-traumatic vestibular dysfunction. However, optimal assessment and treatment practices are poorly evidenced. Using a mixed methods approach, we aimed to explore the feasibility of managing post-traumatic BPPV.
designA mixed-methods randomised feasibility study. In this paper, quantitative and qualitative data relating to key feasibility targets around recruitment, randomisation and assessment and treatment were selected and integrated to provide an in-depth understanding of BPPV management.
settingThree UK major trauma centres
participantsHospitalised adults with post-traumatic BPPV.
interventionsPatients were randomised to one of three interventions (repositioning manoeuvres, Brandt-Daroff exercises and advice).
resultsScreening and recruitment varied between sites due to individual and site-specific factors. Randomisation to advice was experienced differently by healthcare professionals and patients, suggesting that changes to the study design of a future effectiveness trial may be required. Assessment and treatment were acceptable to participants, supporting advancement to an effectiveness trial.
conclusionsIntegration of qualitative and quantitative data revealed new findings relating to the primary outcomes of the feasibility study, while strengths and weaknesses of the trial design were also elucidated. Taken together, such data will influence and enhance the design of a future trial. TRIAL REGISTRATION NUMBER: ISRCTN91943864.
