Abstract：Objective At present,there lacks systematic study on the influencing factors on residual dizziness in patients with benign paroxysmal positional vertigo(BPPV)after reduction therapies.This study aims to identify such factors and introduce a nomogram prediction model.Methods Data from 150 patients with BPPV admitted to the vertigo center in our hospital from January 2020 to December 2020 were selected and divided into a training set(n=112)and a validation Set(n=38).The training set was further divided into a residual dizziness group and a non-residual dizziness group on the basis of presence of residual dizziness after reduction.Multivariate Logistic regression was used for factors influencing post-reduction residual dizziness.Results Compared with the non-residual dizziness group,patients in the residual dizziness group were older,with longer disease duration(＞6 months),higher number of reduction sessions(≥3 times)and higher recurrence rate(P＜0.05),which were identified as independent risk factors for post-reduction residual dizziness.The nomogram prediction model based on these independent influencing factors demonstrated high differential accuracy and clinical applicability.Conclusions Age,duration of disease,number of reduction sessions and post-reduction recurrence are closely related to residual dizziness after reduction in BPPV.
