Seasonality in benign paroxysmal positional vertigo: a systematic review.
Article in BMJ neurology open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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: Benign paroxysmal positional vertigo (BPPV) is the most common cause of dizziness with a lifetime prevalence of up to 2.4%. However, pathophysiology and risk factors for BPPV have not yet been fully clarified. Objective: To systematically examine and discuss seasonal variation in BPPV and the possible relationship between BPPV and climatic variables such as temperature, atmospheric pressure, solar exposure factors, and humidity. Methods: A systematic search was conducted in PubMed and Embase based on a search string with main components BPPV, seasonal variation and climate. Search results were only included if they met the predetermined inclusion criteria. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed, and the AXIS tool was used to assess the quality of the included articles. Results: 12 studies with a total of 18 507 subjects were included. Nine out of 11 studies showed seasonal variation in BPPV, with the majority of these showing an increase in BPPV during the winter months. Four out of six studies showed a negative correlation between temperature and BPPV, three out of four studies showed a positive correlation between atmospheric pressure and BPPV, while three out of five studies showed a negative correlation between solar exposure factors and BPPV. Three out of three studies showed no correlation between humidity and BPPV. Conclusions: Most of the existing literature indicates that there is a seasonal variation in BPPV, with a predominance of BPPV in the winter months. However, the existing literature is only suggestive of the relationship between the examined climatic variables and BPPV.
