Participants: Eligible participants are corresponding authors of clinical trials published between 2010 and 2012 and referenced in Medline.
Intervention: The investigators will evaluate the impact of the presence of a " limitations " section in abstract of systematic review with meta- analysis. The investigators selected abstracts of meta-analysis from a sample.
Selected abstract will be standardised and the treatment's name hidden. Two groups of abstract will be presented as follow: 1) abstract without " limitations " section 2) abstract with " limitations " section. The " limitations " section will be written by authors and will briefly describe the risk of bias of included studies.
Selected participant are invited by e-mail to answer the survey. After reading one abstract from his/her group of randomisation they are invited to answer 5 questions about their interpretation of the results.
