Principal Findings
Our study showed that web-based education about GRADE methodology may not be different to face-to-face education, as measured by the CIL module overall test results. The face-to-face group was better at assessing evidence using the risk of bias. There were no differences between the groups in the overall understanding of the SoF table. Both groups had high levels of satisfaction with the intervention. These results should be evaluated in the context of additional educational resources in EBM courses for medical school students and taking into account a limited sample size.
