I totally agree Lawman. We need a well designed, multi-centered, double blind vs.(control group) trial to make heads turn from the overall market. That being said, the FDA has endorsed a N=30 trial for adjunct..which honestly is quite small..but we will take it. Small "N"'s are great for enhanced expeditious enrollment, however, the small sample size can work against you as well as for you. Say you get 10 bad selection candidates..just by chance. There goes your data...uugh. OR, you are lucky and you get 25 perfect PRO 140 candidates that are potentially high rate respondents...Boom. Especially with a P value equal/less than .05 minimum. (P=.05) is usually standard probability ratio. "N" can be subjected to stronger P values.
