Partial correlation networks among cytokines in the healthy controls (a) and AE patients (b). Note: The colour of the node indicates the origin of the cytokine: red, Th1; yellow, Th2; and orange, both Th1 and Th2.

The solid and dotted lines indicate positive and negative relationships, respectively
