Botulinum Toxin for Cricopharyngeal Dysfunction in Parkinson's Disease

Abstract

a two-year follow-up, 19 ischemic and 25 hemorrhagic events occurred. The optimal achieved INR was between 2.5 and 3.5. We therefore think that the interpretation offered by Powers in his editorial-that it is "unlikely" that "oral an-ticoagulant therapy at some target INR level intermediate between these two levels [those of WARSS and SPIRIT] will be superior to aspirin" 3-is premature.
