I haven't seen any research that supports either. I wouldn't be surprised to learn that code review does nothing other than share knowledge, or to learn that it reduces bugs by 50%. I just honestly have no idea, I do code reviews, because we do code reviews.
In fact I have seen alarmingly little research about code management. Code review, standup, agile, etc. does any of it do anything useful? I only came across anecdotal evidence which can be dismissed.
