This poor misguided author, Dr. Olivier, does not appear to understand crossover confoundment (randomization confoundment as a direct consequence), immunotherapeutic delayed impact, pseudoprogression, unprecedented long term survival and the ethical implications of denying crossover, and yet he defers to Temodar as the gold standard when it typically achieves only 3% five year survival.
He does use googly eyes on Twitter to draw attention to his journal article. Perhaps he missed his calling.
