Welcome to MedStats.Org
MedStats.Org: On all things ‘medstats’
Are you new to medical research?
Do you need to top up your medstats skills: research methods, study design, data analysis (statistical analysis), sample size calculation and power calculations?
Do you know which statistical software you could use for your data analysis and power calculations?
Do you know how to interpret those results: the p-value, the 95% confidence intervals, the odds ratios?
You have come to the right place. We have tutorials and, interactive tools and calculators that make learning and using medical statistics (medstats) fun! The interactive tools and calculators cover some of the key statistical concepts and terms commonly used in medical research. You need to understand these when planning your research project, as well as when reading research articles from medical journals. These subjects also feature commonly in postgraduate medical exams, such as the Royal College Membership and Fellowship exams. Topics covered include:
- Sensitivity & Specificity
- Positive Predictive Value (PPV) & Negative Predictive Value (NPV)
- Odds Ratio & Risk Ratio
- Number Needed to Treat (NNT) & Risk Reduction
- The effect of disease prevalence on PPV and NPV, and
- Freeman – The role of p-values in analyzing trial results, are some of the tutorials available.
