I am far less 'in the know' than many here but I don't understand how this could present a legitimate question posed in good faith.
Somebody noted that a doctor with a competing brain cancer trial may be inclined to be critical of NWBO for the benefit of his own competing trial.
For your Rago comparison to apply, I would require Rago to be a doctor directly involved in the NWBO trial as a participating doctor. I reject the premise that the comparison is appropriate simply because he possesses a medical degree, but is not involved in the Trial as a participating physician.
