Fig. 3: Subjective evaluation and follow-up outcomes comparing AI and doctor groups.

A Patients in the AI group reported significantly higher post-discharge satisfaction, expectation alignment, and knowledge scores compared to the Doctor group, reflecting improved patient education and engagement. B At the 1-month follow-up, the AI group showed significantly greater improvements in function and physical health, while GAD-7 and MCS scores were comparable between groups. C At 3 months, the AI group continued to outperform in function and PCS, indicating more sustained physical recovery benefits, but no significant differences in GAD-7 or MCS were observed. D By 6 months, all outcome measures showed no significant differences between the groups, suggesting convergence in long-term outcomes. E, F Pie charts illustrating the distribution of patient questions in the AI group and Doctor group, categorized into the following question types: (A) Symptom consultation, (B) Surgical information, (C) Postoperative care, (D) Postoperative recovery, (E) Medication consultation, (F) Postoperative complications and recurrence, (G) Lifestyle recommendations, (H) Other questions.
