Model performance comparison from demographic only to additional CSF. Comparison of model performance of the stepwise approach (black) from demographic 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
