Fig 4. Conditional inference tree of preoperative MoCA and perioperative PDQ-39 SI changes.

Fig 4

A: Conditional inference tree revealed a three-fold partitioning of patients by the pre-MoCA score. Patients scoring ≤ 23 in the pre-MoCA had a decline of post-PDQ-39 SI. Pre-MoCA scores 23–26 resulted in a slight, but significant improvement of post-PDQ-39 SI. Patients >26 points showed the most reliable, positive post-PDQ-39 SI improvement. B: A pre-MoCA >23 points resulted in an improvement of quality of life. Patients with a pre-MoCA < = 23 showed a postoperative decline of quality of life. Pre: preoperative; post: postoperative; SD = standard deviation; N = number; % = percentage of patients; mean = Δ PDQ-39 mean; Δ PDQ-39 = difference of preoperative PDQ-39 SI minus postoperative PDQ-39 SI; Error bar = ± 1 standard deviations.
