Fig. 2From: Biomarker testing in MCI patients—deciding who to testModel performance comparison from demographics and MRI to additional CSF. Comparison of model performance of the stepwise approach (black) from demographic and MRI information (red) only to additional CSF testing (blue). a. Prognostic discrimination measured with cross-validated Harrell’s C. b. Prognostic accuracy measured with cross-validated 3-year brier scores. A lower brier score indicates a better prognostic accuracy. CSF, cerebrospinal fluid; MRI, magnetic resonance imagingBack to article page
