Registering systematic review in Prospero I have recently submitted a systematic review (SR) to a journal. One of the reviewers pointed out, that my SR was not registered in Prospero, an international prospective register of systematic reviews. While I agree it would have been of good practice to register my SR, my current understanding is that registration of SR is not yet mandatory¹.

How can I address this reviewer’s remark?

First of all, If you don't think it's mandatory, and you don't want to do it, just say it's intentionnal.

Since, as you said in comments, this database is apparently used when you plan to undertake a SR, it would have no value for you to register in it, since you are already in SR.

But you may ask the reviewer why he got the urge for saying that , and if he thinks it would be interesting for you to register on it anyway.
