Issues and debates within evidence-based healthcare

Health in the media series

We’re also looking for students to start up our ‘health in the media’ series again, looking at the claims made in the media about various interventions and evaluating whether these claims are true to the evidence.

Reviews of resources

We’re also looking for students to write short, informal reviews of learning resources, giving feedback on how useful they find them. You can find more information here. 

Evidently Cochrane

Evidently Cochrane, our sister blogging website, are also looking for bloggers and have a list of suggested blog topics on their website.
