IL6, GFAP, CX3CL1, and ICAM1 were significantly increased compared to preoperatively in the patients with postoperative delirium (Table S4d), and CHI3L1 and VIM were significantly decreased postoperatively in the patients with delirium compared to preoperatively, but only IL6 significantly rose in the patients without delirium compared to preoperatively (Table S4b and d). Here, VIM is linked to delirium.
