Figure 1. Stratification of patients with rheumatoid arthritis.

Figure 1

Stratification of patients with rheumatoid arthritis (RA) can occur at several points during the natural history of the disease. Stratification describes a process of characterising subgroups of patients according to distinct clinical, cellular and molecular features (or endotypes) using any combination of parameters. Multiple platforms can be adopted to stratify patients throughout the disease course, including serotyping, clinical and immunological phenotyping, genotyping and imaging.
