Schematic of heterogeneity in clinical presentation and disease course. Left: Theoretical 3D landscape depicting the risk of type 1 diabetes in an individual (vertical dimension) driven by the complex relationships between both known and unknown factors, including genetics, immunity, and metabolic and β-cell parameters (horizontal dimensions). Right: Individual risk landscapes are modified by sources of variation such as age and BMI. Each individual’s risk continues to vary due to environmental exposures and the passage of time, increasing the overall heterogeneity of subject cohorts.
