Session Abstract

Session Synopsis: Health practitioners ground clinical decisions for an individual patient on data garnered from patients with similar characteristics, or so called subgroups or subsets. The idea is to reference each individual patient against a population of otherwise similar patients to answer clinical questions about that patient’s health state, disease trajectory, and likely response to treatment. The goal of “subsetting” is to create increasingly homogenous groups of “otherwise similar patients” against whom to reference the individual patient. This session will discuss the learnings from analyzing subgroups and tying it to the biology of the system.
