CSF catecholamine levels in delirium sub-grouped according to pre-fracture dementia status. (A–C) Among patients without pre-fracture dementia (A) CSF noradrenaline was although not significant higher in incident delirium (n = 7) compared to those with no delirium (n = 43; P = 0.08). (D–F) There were no significant differences among pre-fracture dementia patients. Larger and smaller lines represent median and interquartile range respectively. Two-tailed P-values are obtained by Mann–Whitney U-test.
