That's quite outrageous. If this special issue was peer-reviewed, people donated their time for free to publish 11 studies with potentially severe conflicts of interest. If the issue was not peer-reviewed, then the editors handed out free publication for money, which is what predatory journals do. There is no way to spin this as remotely related to good scientific practice, which would mean: - Funding is independent of results - Double-blind peer review - Pre-registration wherever possible
