Fig. 5: Subgroup analysis of joint replacement patients in AI and doctor groups.

A At discharge, patients in the AI group reported significantly higher satisfaction and knowledge scores compared to the Doctor group, although expectation scores were similar. B At 1-month follow-up, the AI group showed significantly better functional outcomes and higher physical health scores, while no significant differences were observed in anxiety or mental health. C These functional and physical advantages were maintained at 3 months, as evidenced by persistently higher FJS and PCS scores in the AI group, with no group differences in GAD-7 or MCS. D By 6 months, outcome measures across all domains were comparable between the two groups.
