Table 2. Changes in QoR-40 Scores over Time in Cranial Surgery Patients
Scores are presented as mean (SD). SRM = standardized response mean = mean change in score divided by its SD, referenced to day 90 (“full recovery”). SRMs of 0.2, 0.5, and 0.8 correspond to small, medium, and large changes in quality of recovery (QoR)-40 scores, respectively.
