Figure 1 Study flow diagram. (1) Alzheimer’s disease: Diagnosed by clinical evaluation or neuropsychological testing; exclusion due to inability to provide reliable self-reported outcome measures (VAS, sleep quality). (2) Postoperative pulmonary infection: Resulted in prolonged hospital stay; interfered with the assessment of core outcomes due to altered postoperative recovery trajectories. (3) Absence of quantifiable data: Two patients (ropivacaine group) were excluded due to a complete lack of retrievable VAS or sleep quality scores at all postoperative time points.
