Fig. 4From: Supporting the differential diagnosis of connective tissue diseases with neurological involvement by blood and cerebrospinal fluid flow cytometryMultivariable models of immune cells differentiate N-CTD from MS with high discriminatory capacity. A–D Lasso regression was fitted on the blood (A, B) and CSF (C, D) parameters to classify N-CTD and MS. Predictors with positive predictor importance values (A, C) are colored in red. High values of these parameters increase the probability of N-CTD. Predictors with negative values are colored in blue and high values increase the probability of MSBack to article page
