Abstract
The diagnostic value of individual items in the patient medical history for identifying benign paroxysmal positional vertigo (BPPV) remains largely unexplored. This study aimed to construct and validate a disease prediction model to identify useful questions for suspecting BPPV. Patients presenting with dizziness were enrolled, with 290 participants for model construction and 61 for validation. The study specifically targeted BPPV of the posterior semicircular canals with a positive Dix–Hallpike test (DHT + BPPV). Binomial logistic regression analysis identified "duration of dizziness ?15 seconds" and "onset when turning over in bed" as independent predictors of DHT + BPPV. Affirmative answers to both questions yielded a likelihood ratio for diagnosis of DHT + BPPV. These findings highlight the importance of these historical features in suspecting and diagnosing BPPV
