Supplementary file 1_Comparison of clinical outcomes and quality of life for robotic versu

Lei Zhang's supplementary data compares clinical outcomes and quality of life for robotic-assisted versus laparoscopic surgery in elderly patients with mid-low rectal cancer. The dataset likely contains results from a multicenter cohort study of 1,023 patients aged 70+ from two tertiary centers, analyzed using inverse probability of treatment weighting. The data was last updated on 2026-04-21.

Use Cases

• Compare intraoperative outcomes like estimated blood loss and complication rates between surgical approaches.
• Analyze postoperative complication rates, including specific incidents like urinary retention.
• Model longitudinal quality-of-life metrics such as urinary, defecatory, and male sexual function over a 12-month follow-up.
• Assess cancer-specific survival benefits, particularly for patients with T4 stage tumors.

Strengths

• Data is derived from a study of 1,023 consecutive patients aged 70 years or older.
• Analysis includes a 12-month longitudinal assessment of quality-of-life metrics.
• Study employed inverse probability of treatment weighting for balanced cohort comparison.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic or institutional bias inherent to the two participating centers.
