The authors respond:

We thank the authors1 for their interesting comments in defense of their proposed guidelines. However, we judge their remarks to be about semantics, not substance. The authors themselves have previously stated that PRISMA advocates protocol registration.2 In our view, the main issue is not whether PRISMA “demands,” “advocates,” or “requests” registration. If the guideline was adopted as standard by journal editors, the “request” would of course become a requirement, and the real question is whether this requirement makes sense. Our view, as detailed in our original commentary,3 is that it does not: this additional layer of academic bureaucracy would merely obstruct free scientific enquiry.
