 Armstrong suggested Betsy may have been confused by possible mention of his post-operative treatment, which included steroids and EPO that are taken to counteract the side effects of intensive chemotherapy.The Andreus' allegation was not supported by the eight other people present, including Armstrong's doctor Craig Nichols, or his medical history.According to LeMond, he had recorded a conversation, transcribed for review by NPR, in which Armstrong's contact at Oakley, Inc., Stephanie McIlvain, corroborated Betsy's account.
