The Correlation Between Patient Satisfaction and Postoperative Subjective Happiness Scale (SHS)/Changes in SHS/Pittsburgh Sleep Quality Index (PSQI). (a) The patient satisfaction is correlated significantly with the postoperative SHS score (r = 0.324, P < 0.001). (b) The patient satisfaction is correlated significantly with the changes in the SHS score (r = 0.157, P = 0.013). (c) The patient satisfaction is correlated significantly with the postoperative PSQI score (r = −0.144, P = 0.024).
