S1 File: Ventral Hernia Repair Outcomes for 6,207 Patients via Propensity Matching

6,207 patient records from the ACS-NSQIP database comparing open and robotic component separation techniques for ventral hernia repair. The dataset includes 30-day complication rates, length of stay, and readmission data, analyzed with multivariable logistic regression and propensity score matching. Author Silvana Maldonado published the data on figshare in April 2026.

Use Cases

• Compare 30-day complication rates between surgical techniques based on the described outcome categories.
• Analyze associations between robotic surgery and shorter length of stay based on the reported statistical results.
• Model risk factors for postoperative complications using the propensity-matched cohort described.
• Benchmark readmission rates for ventral hernia repair procedures based on the provided data.

Strengths

• Includes data for 6,207 patients with a clear breakdown of 4,443 open and 1,764 robotic cases.
• Results are supported by propensity score matching on 5,259 patients and multivariable regression.
• Contains specific outcome metrics like overall complication rates (4.8% vs. 19.6%) and length of stay (1.34 vs. 3.86 days).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying raw data is unknown, which may limit suitability assessment.
• Data is retrospective and from a specific registry, which may reflect inherent selection biases.
