> Here is a phase 3 that succeeded and failed. Clearly it works. That's not clearly works. Quantifying works/succeed with statistic is how you know it clearly works because it's statistically significant. Other wise your clearly work statement is just your opinion and the opinion of a drug company trying to make money. If it fail and succeed in phase 3 then it's not clear at all if it works.
