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!
