Join Cochrane Crowd and become a Cochrane citizen scientist. Anyone can join our collaborative volunteer effort to help categorise and summarise healthcare evidence so that we can make better healthcare decisions. No experience necessary! You can do it from the comfort of your home and just five minutes a week will make a difference. In the last 20 years research output has grown exponentially making it really difficult to keep up with the evidence. As a Cochrane citizen scientist you would be helping us to identify and describe the research that may be very important in helping us to determine whether a treatment works, or whether a diagnostic test is accurate. We're a growing community of over 4000 people from 88 countries and we've categorised over 1 million research records since February 2016. Join our growing community of Cochrane citizens and together let's find those trials!
