Course Highlights
Mortality rates are amongst the most important indicators in epidemiology. They are used when trying to express the risk of dying from a certain disease. In this video from Epidemiology Essentials, Franz Weisbauer explains the nuts and bolts of mortality rates; how to calculate mortality rates for various subgroups; the concept of proportionate mortality; and understand why proportionate mortality is not a measure of risk.
Positive predictive value (PPV) and specificity
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 prevalence
In this video, Franz Wiesbauer looks at how a doctor can work out the probability of disease when confronted with a positive or a negative test result and how the prevalence of a given disease affects this probability.
In this video, Franz Wiesbauer explains how to express prognosis with the help of life tables and why this is essential to understanding Kaplan Meier curves.
