If you're working on a literature review that is meant to be completed in a systematic fashion (e.g., you're following a pre-determined protocol, driven by an established guidelines, and you'll be reporting according to PRISMA standards), you will need to track your references carefully, tracking the total number of references located by database searching, the number of duplicates from different databases, and how many records are excluded after each screening phase. Citation managers like EndNote and Zotero are useful for these processes, but Covidence is designed for systematic reviews, allowing you to manage the workflow more seamlessly.

If you are using a citation manager to store bibliographic data related to your evidence synthesis project, it is recommended that you maintain back up copies of your data.
Recommended steps for backing up bibliographic data will vary depending on your software of choice (Zotero, EndNote or RefWorks) - more information can be found on the guide for Data Management Planning - Storage & Backup.
