(A,B) Estimated mean total DHI and VSS scores in unilateral vestibulopathy patients who did not receive intervention. This includes DHI and VSS scores from studies without an intervention, as well as pre-intervention DHI and VSS scores from interventional studies. The dashed lines on the forest plots represent the overall pooled estimates. The black squares indicate the mean scores of each study and horizontal lines represent their 95% confidence intervals. The size of the black squares represents the weight contributed by each study in the meta-analysis. The black diamonds refer to the pooled odds ratio and their 95% confidence intervals. DHI, dizziness handicap inventory; VSS, vertigo symptom scale; Q, Cochran’s Q statistic; df, degrees of freedom; I², Higgins’ calculation; CI, confidence interval.
