ADIPOQ and delirium: In the longitudinal analysis, there were no differences in the levels of any of the markers immediately prior to and following the onset of delirium, but overall, median levels of adiponectin (9019 (IQR 5776–15,442) vs. 6148 (IQR 4447–8742) ng/ml, p = 0.05) were significantly higher in patients with delirium compared to patients without delirium.
