Fig. 3From: Supporting the differential diagnosis of connective tissue diseases with neurological involvement by blood and cerebrospinal fluid flow cytometryBlood plasma cells can distinguish N-CTD from CTD. A–D The AUC (area under the curve) values of the ROC analysis of N-CTD vs. CTD in the blood (A) and the CSF (C), and of N-CTD vs. MS in the blood (B) and the CSF (D) are visualized in a heatmap sorted by AUC value. Possible AUC values range from 0.5 (uninformative) to 1 (perfect) and measure the discriminatory ability (combined specificity and sensitivity) of the parameterBack to article page
