Study limitations and strengths
The main limitations of this study arise from its retrospective character and the associated bias. Additionally, patient notes extracted were not randomised, and as such our results may not be entirely representative of the BPPV population.
Additionally, we did not include further factors that could play a role, such as vitamin D levels, which have been shown to play a role in recurrences and their severity.
On the other hand, the present study is powered and the only study looking into the impact of socioeconomic factors on BPPV, shedding some light on the commonest peripheral cause of dizziness.
