Figure 4. Forest plot of effect size by steroid treatment for vestibular neuritis. (A) Therapeutic effect of steroid was analyzed according to follow-up period after onset. In this analysis, subgroups were classified into short-term (1 month), mid-term (3 & 6 months), and long-term (12 months). (B) The therapeutic effect of steroids was analyzed according to comparator. One comparison design was steroid versus non-steroid groups and the other was combination therapy of steroid and other treatments versus other treatment alone. (C) The therapeutic effect of steroid was analyzed according to outcome measures. In this analysis, outcome variables were complete caloric recovery, improvement of canal paresis, and dizziness handicap inventory score.
a, improvement in lateralization caloric test; b, complete caloric recovery; c, dizziness handicap inventory score; d, after 1month; e, after 3 months; f, after 6 months; g, after 12 months; h, steroid group versus non-steroid group; i, combination therapy of other treatments with the steroid versus other treatment only
