Join Cochrane Crowd for the Cochrane Colloquium Challenge 2019!

Cochrane Crowd are running a citation screening challenge to coincide with the Virtual Cochrane Santiago Colloquium! Help Cochrane Crowd reach 48,000 classifications in 48 hours and be amongst the first to try out the all new, shiny CINAHL task! Details on this and how to join in below.

When is it running?
Start: Wednesday 4th December at 11:00 am GMT
Finish: Friday 6th December at 11:00am GMT
You can check what time that is for you here

How much time do I have to commit?
Of course, we’d love you to do the whole 48 hours! Just kidding. Any contribution is welcomed, whether it be a few five-minute grabs or a more focused effort (so you better make sure you have some screening snacks to hand to keep those energy levels up).

Sounds good so far. But I’m new to Cochrane Crowd. What is it all about?
Your best bet is to watch our 2-minute video introduction here.

What is the new CINAHL task?
For this challenge we want you to help identify possible reports of randomised trials (RCTs) that we have retrieved from a source called CINAHL. We haven’t identified RCTs from this source before. CINAHL is THE source for nursing and allied health professional research.

If I join in, what will I be doing?
Your mission for this challenge is to assess those records from CINAHL and decide whether you think they are describing a randomised trial or not. There will be a brief training module to complete if you haven’t done this kind of task before task before. Once identified, these studies go into a central register where health researchers and practitioners can access them.

Will there be prizes?
Of course! We’re glad you asked! Yes, prizes will go to the top three contributors. What are the prizes, you ask? A snazzy (limited edition!) T-shirt and a highly readable book – it’ll be like Christmas come early!

How do I sign up for the challenge?
There is no need to sign up for the challenge per se. You can just head to Cochrane Crowd anytime during the 48 hours of the challenge and get cracking!  If you’ve not been to Cochrane Crowd before, then you can sign up here.

Sounds fun, can I tell all my friends about it and get them to join in?
Yes please! We want as many as possible to join us. Feel free to share this page (share buttons below).

Is there a Twitter hashtag?
