PheValuator provides phenotype definition performance statistics such as sensitivity, specificity and PPV. PPV depends on the prevalence of the phenotype in the datasource. Prevalence in terms depends on the population in the datasource and the observation period per person in the datasource. PPV may thus vary by datasource.

It would be nice to have an output on the relationship between prevalence and PPV similar to as described here https://newonlinecourses.science.psu.edu/stat507/node/71/ .
