Multiple logistic regression analysis showed significant effect of ENoG value on recovery in both Bell's palsy and <jats:styled-content style=\"fixed-case\">RHS<\/jats:styled-content>. Values of ENoG were significantly worse in RHS than Bell's palsy. Chance of early recovery within 6 weeks after correction of ENoG effect was still significantly worse in RHS.
