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
