Fig 2. Model validation.
Observed versus predicted validation endpoints (internal and external) and validation to published T1DM model output (costs and quality adjusted life years). Overall validation coefficient of determination for clinical endpoints, R2 = 0.863; internal R2 = 0.999; external R2 = 0.823; total costs R2 = 0.979; total QALYs R2 = 0.951.
