Propensity score matching methodology: why and how it is used
Learn more about propensity score matching and how it is used to evaluate data in observational studies that do not have an internal comparator in this animated video. To find out more about how the methodology was used to evaluate effectiveness data from a patient drug registry and an open-label study, please refer to the two research articles cited below, which were originally published in the Journal of Comparative Effectiveness Research.
