Help us find the evidence: become an Embase screener

The EMBASE project provides an opportunity for new and potential contributors to get involved with Cochrane work by diving into a task that needs doing. No prior experience is necessary as the task supports a ‘learn as you do’ approach.

The project’s purpose is to identify reports of randomised controlled trials (RCTs) and quasi-RCTs from EMBASE for publication in the Cochrane Central Register of Controlled Trials (CENTRAL).

A web-based screening tool has been developed so that anyone, with access to the internet, can join the collective effort to screen the search results for relevance within CENTRAL. A quality-control system has been developed so that all records will be viewed by at least two screeners. Records viewed by new screeners will need three consecutive agreements on the record’s relevance for it to then be either published in CENTRAL or ‘rejected’. Disagreements will be arbitrated by highly experienced screeners.

This task has been designed so that it fits around people’s busy lives and they can dip in and out as suits them.

By the end of 2014, over 800 volunteers had signed up and collectively screened more than 100,000 records identifying over 3,500 RCTs.

Interested? Then simply:

  1. Click on this link which will take you the screening tool:
  2. You’ll then need to create an account (which will take about a minute to do)
  3. Start screening – 20 practice records first, which you can do as many times as you like, and then onto ‘live’ records
