NCT04380428

Brief Summary

This study is an online survey to assess risk literacy among students of the medical and dentistry faculties in Portugal. Risk literacy is the capability to understand and interpret statistical information, based on simple rules of thumb. The investigators assess the level of "medical risk literacy" among Portuguese medical and dentistry students with the Quick Risk Test (QRT) and the multiple choice version of the Berlin Numeracy Test (BNT).
