CSI cut-off scores, comparing patients diagnosed with a CSS (N=89) and non-patient comparison subjects, excluding those who reported a CSS on CSI part B (N=105)

Sensitivity: The proportion of actual positives which are correctly identified

Specificity: The proportion of negatives which are correctly identified

Area under the curve: Excellent: 0.90-1.00/ Good: 0.80-0.90/ Fair: 0.70-0.80/ Poor: 0.60-0.70/ Fail: 0.50-0.60
