Approaches to Simultaneous Analysis of Frequency and Severity of Symptoms

Mechanistic models that synthesize pharmacological and (patho)physiological process information provide a rich basis for the characterization of drug action. However, the underlying clinical data are often simplified in a manner that does not allow models to fully elucidate the structure of the drug effect. In this article, we describe data‐simplification strategies that are in routine use to describe disease symptoms and compare them with a model developed for handling the true complexities of the data.
