Just reading a spoon few article does not take two years.
Reviewers would know based on their own work in the field whether Dr. Bosch was engaged in a conflict of interest or not and for all we know making sure that was not a problem along with scrutinizing other issues before saying it was okay could have helped drag this JA out those two years.
It would seem to me that just like they could consult any articles cited by NWBO in the JA to verify that they say what they are said to say, the reviewers can and should look at any official information about the trial and that would allow them to see the screening halt.
So in short, your questions were good before peer review but by getting peer review NWBO removed those issues.
How do you know what JAMA Oncology saw and what they did not see? The reviewers are independent physicians and independent people who are allowed to see anything they wish to see.
Your statement could not possibly be true.
JAMA is not allowed to see certain information that only HyGro is allowed to see?
