Treatment and recurrence of traumatic versus idiopathic benign paroxysmal positional vertigo: a meta-analysis
Bibliographic record
Abstract
Background: So far, there has been a controversy surrounding repositioning difficulty and recurrence rate between traumatic benign paroxysmal positional vertigo (t-BPPV) and idiopathic BPPV (i-BPPV).Objectives: This meta-analysis was aimed to explore whether or not the differences between t-BPPV and i-BPPV in the repositioning difficulty and recurrence rate existed.Material and methods: A literature search was performed in the databases including Pubmed, Embase, CENTRAL, which completed in 21 January 2019, with no restriction of publication language. Relative risk (RR) of number of repositioning maneuvers and the recurrence rate was calculated with its 95% confidence interval. Sensitive analysis was performed simultaneously.Results: Six retrospective cohort studies were included in our meta-analysis, including 865 t-BPPV patients and 3027 i-BPPV patients. All studies were high quality according to Newcastle-Ottawa Scale (NOS) assessment. Patients with t-BPPV required more repositioning maneuvers for resolution than those with i-BPPV (RR = 3.27, 95% CI = 1.88–5.69, p < .0001), and the recurrence rate of t-BPPV was higher than that of i-BPPV (RR = 2.91, 95% CI = 2.04–4.14, p < .00001).Conclusions and significance: Compared with i-BPPV, patients with t-BPPV require more repositioning maneuvers to resolve, and the recurrence of t-BPPV was more frequent.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
