^aP < 0.05 vs good preoperative sleep quality group [Pittsburgh Sleep Quality Index (PSQI) score 0-5].

^bP < 0.05 vs preoperative group without depressive symptoms (Hamilton Depression Rating Scale score 0-7).

Assessment of sleep quality (PSQI scores) in 102 patients undergoing laparoscopic hysterectomy under general anesthesia. Data presented as mean ± SD. P < 0.05 indicates statistically significant difference. PSQI: Pittsburgh Sleep Quality Index; HAMD: Hamilton Depression Rating Scale; BMI: Body mass index.
