In order to avail of Covidence without charge for registered Cochrane reviews, you will need to link your review to your Cochrane account.
To do this, first make sure you are logged in to Covidence using Cochrane (see this article for how to do this!). You'll see the available titles in a drop-down box.
Note that in order for Covidence to find this title, it needs to meet the following criteria:
* Stage is "full review" or "protocol"

* Phase is "authoring"
* The individual performing the search has the "author" or "author support" role
When the review is successfully linked to Cochrane, it will appear with a Cochrane logo next to it in your review list (see attached image). This will enable you to invite unlimited co-reviewers.
