Training Course Syllabus

Using the CASP Statistics Workbook and published data from a randomised controlled trial, learners will have the opportunity to practise how to calculate odds ratio, risk ratio, relative risk reduction, absolute risk reduction, and number needed to treat.

This micro module looks into the key performance metrics for evaluating the outcomes of randomised controlled trials, such as absolute and relative risk, odds, and number needed to treat or harm. It also emphasises the significance of confidence intervals (CIs) and P values in assessing the findings of published research to assess if the benefits of the results outweigh the potential risks to a given population.

The ‘Making Sense of Results: Measures of Effectiveness in Randomised Controlled Trials’ course covers:

  • Interpreting results
  • Results expressed as a difference

  • Relative vs. absolute measures
