The vast majority of results were not only not accurate, couldn't possibly have been accurate given the methods they were using to conduct the tests. This is well documented. I suggest John Carreyrou's book, _Bad Blood_, which gets into great detail on this.
Once again, just because some dude wrote it down in a book doesn't mean it's a fact. The jury just acquitted her of those charges. Maybe they didn't the read dude's book?
The jury made no judgements as to the efficacy of the tests. In fact, both the prosecution and the defense stipulated that the Theranos project was a failure. The defense even stated that "Failure is not fraud." The question before the jury was whether or not she had defrauded investors.
They decided that she had.
FWIW, every single firm that had medical expertise declined to invest in Theranos. They could see it had extremely minimal chance of success.
