From: Alcohol consumption may be associated with postoperative delirium in the elderly: the PNDABLE study
Expression of CSF biomarkers and alcohol consumption of POD patients and non-POD controls. The scatter plots showed the expression levels of Aβ40 (A), Aβ42 (B), P-tau (C), T-tau (D) and alcohol consumption (E). The colors of scatter maps are grouped according to different diagnostic groups. The P value was determined by the two independent samples t-test. The level of CSF Aβ42 and alcohol consumption in patients with POD (POD group) were significantly different than those in patients without POD (NPOD group) (P < 0.001)
