Introduction: Statistics and a good understanding of numbers are important professional tools for doctors in order to understand and communicate risk estimates. Materials and methods: In this questionnaire survey carried out among 129 specialist trainees the ability to calculate and compare risk values (Relative Risk Reduction, Absolute Risk Reduction, Number Needed to Treat and a combination of these) was examined along with the general understanding of numbers in relation to probabilities. Results: The survey showed that 69% of the participants were able to calculate a risk reduction accurately. Answers from the respondents did not depend on whether information was given as absolute or relative risk reductions. 13% of the participants were able to correctly estimate the risk of a false positive answer in connection with screening. Conclusion: The trainee doctors demonstrated a surprisingly poor ability to make basic probability calculations and a poor understanding of screening results. A thorough understanding of risk measures as well as basic probabilities is a prerequisite for good objective patient information. This survey indicates that there is considerable room for improvement in these areas.
