Nobody knows exactly what the numbers will be. It appears that the company is confident they will be in the 90s. In today's blog, he noted that even the much maligned data that came out Tuesday showed 90% accuracy for AD vs cognitively intact. Those 44 people in that study included various dementias. AD vs cognitively intact looked pretty good in that small sample. The Bridge Study is only comparing AD vs cognitively intact so I think they feel pretty good about seeing numbers in the 90s, but until the data is ready and presented, nobody can say for sure what it will be.

I think the main point is that raw data from a poorly run (for lack of a better term) study by Provista when followed up on 7 years later looked decent enough to hypothesize that a study that is run in a better manner will produce better results.

At least that's my interpretation. Feel free to respond if you think I'm off base.
