Brief Summary:

Objective: The investigators aim to evaluate the impact of a adding a " limitations " section in systematic review's abstract on result's interpretation by readers Design: randomized controlled trial with two parallel arms. Participants will be invited to participate in an online survey.

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.

Arm Intervention/treatment
Experimental: abstract with limitation section added
we add a limitation section in each selected abstract, the limitation section will focus on the quality of included studies.
Behavioral: interpretation of the abstract of the systematic review

Primary Outcome Measures :
  1. confidence in the results of the systematic review [ Time Frame: 1 month ]
    we ask participants: "how confident are you in the results of this study?", with the choice of answer based on a 10 points Likert scale


Secondary Outcome Measures :
  1. interpretation of the quality of the systematic review [ Time Frame: 1 month ]

    We ask participants:

    • "How confident are you in the validity of the conclusions of this study?"
    • "How confident are you that the intervention "A" could be of benefit to patients?"
    • "How confident are you that the results of this study could influence your clinical practice?"
    • "Do you think that this systematic review was conducted rigorously?"

    with the choice of answer based on a 10 points Likert scale
