Serum Vitamin D Levels and Prognosis in Benign Paroxysmal Positional Vertigo

286 patients diagnosed with benign paroxysmal positional vertigo (BPPV) between January 2021 and December 2025 were studied to evaluate the association between baseline vitamin D levels and clinical outcomes. The retrospective cohort data includes serum 25-hydroxyvitamin D measurements categorized as deficient, insufficient, or sufficient, linked to 1-week response rates, recurrence, and Dizziness Handicap Inventory scores. Zhen Rao published the dataset on figshare under a CC-BY-4.0 license in June 2026.

Use Cases

• Predicting short-term treatment response based on baseline serum 25-hydroxyvitamin D levels.
• Analyzing the association between vitamin D status and recurrence rates of benign paroxysmal positional vertigo.
• Modeling the relationship between vitamin D levels and the burden of repositioning maneuvers required for treatment.
• Investigating correlations between vitamin D categories and patient-reported outcomes measured by Dizziness Handicap Inventory scores.

Strengths

• Dataset includes 286 patient records from a defined cohort diagnosed between 2021 and 2025.
• Primary and secondary outcomes are clearly defined, including a 1-week response rate of 50.7% and recurrence rate of 21.3%.
• Statistical analysis results, such as adjusted odds ratios and confidence intervals, are provided in the description.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal and source bias inherent to a single retrospective study from figshare.
