Classification of LGDH, LKYD, and HC groups by cytokines. a Plots representing the models discriminating the LGDH, LKYD, and HC groups. The metric multidimensional scaling (MDS) represents the proximity matrices of the RF models, which demonstrate the relationships among the three cohorts. The two axes represent the first and second MDS axes. Red dots LGDH patients; blue dots LKYD patients; green dots HCs. b Relative importance of the cytokines in the overall classification. The vertical axes represent the arrangement of individual cytokines according to their importance. The horizontal axes represent the average decrease in classification accuracy as the Gini scores. The important cytokines were associated with a greater decrease in classification accuracy.
