Figure 3. The postoperative delirium severity in the 1st quartile and the combination of the other three quartiles of CSF Aβ40/Tau or Aβ42/Tau ratio.
A. Mann-Whitney test suggests that there is a significant difference in the highest MDAS score between the 1st quartile (red bar) and the combination of the 2nd, 3rd, and 4th quartiles (blue bar) of CSF Aβ40/Tau. B. Mann-Whitney test suggests that there is a borderline difference in the highest MDAS score between the 1stquartile (red bar) and the combination of the 2nd, 3rd, and 4th quartiles (blue bar) of CSF Aβ42/Tau ratio.
