Medmastery: PPV and Specificity
The team at Medmastery are providing LITFL readers with a series of FOAMed courses from across their website. Over the next few weeks, we’ll be posting videos from their Epidemiology Essentials course.
In this video, Franz Wiesbauer looks at the impact of specificity and sensitivity on positive predictive value (and thus validity of a test) and why one has a bigger impact than the other.

- Positive predictive value (PPV) and specificity
- Positive predictive value (PPV) and prevalence
- Prognosis and life tables
