Weather and Seasonality Associations With Vestibular Neuritis.
Article in Cureus, 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
backgroundVestibular neuritis (VN) is an acute vestibular syndrome often attributed to viral or post-viral inflammation, though evidence for seasonal or environmental triggers remains inconsistent. While early studies suggested spring or summer peaks, more recent data have questioned whether VN incidence follows a clear seasonal pattern. Beyond broad seasonality, specific meteorological factors may influence VN occurrence.
objectiveThis study aims to investigate seasonal variation and associations between VN incidence and local weather anomalies in a Mediterranean climate.
methodsWe retrospectively reviewed VN cases presenting to a tertiary hospital in Patras, Greece, between January 2020 and September 2025. Diagnoses were based on Bárány Society criteria. Daily meteorological data (temperature, wind speed, atmospheric pressure) were obtained from Meteostat and aggregated by month. We assessed seasonality with a chi-square goodness-of-fit test and calculated Pearson correlations between monthly VN cases and weather anomalies (deviations from long-term monthly means). Bonferroni correction was applied for multiple testing.
resultsA total of 102 VN patients were identified (mean age, 54.7 ± 15.4 years; 58 (56.9%) female cases). No significant seasonality was observed in monthly case distribution (χ² = 14.58, p = 0.2). However, maximum temperature anomalies were positively correlated with VN cases (r = 0.39, p = 0.0009; Bonferroni-adjusted p = 0.0047). Wind speed and average temperature anomalies demonstrated a negative and positive correlation with VN cases, respectively (p < 0.05), which did not reach significance after Bonferroni correction (p > 0.01). Other meteorological variables showed no significant associations.
conclusionThe incidence of VN in our cohort did not follow a strict seasonal pattern but was significantly associated with higher-than-average monthly maximum temperatures. This supports a multifactorial pathogenesis in which viral reactivation, vascular compromise, and immune dysregulation may interact with environmental stressors. These findings highlight the importance of considering climatic influences in VN and warrant further multicenter, high-resolution studies integrating virological and environmental data.
