My co-author was very apprehensive about screening having screened around 500 for his masters and it was a complete nightmare using a traditional reference management program – it’s also his first Cochrane Review! But he found it easy to use Rayyan and was quickly able to include and exclude the reviews. Thank you for such a great tool!

My colleagues and I, are very pleased with Rayyan. We have used Rayyan in a couple of projects, and the text mining function works well. We are looking forward to future developments.
