Meta-Analysis of Risk Factors for Hernia Repair Complications from 11 Studies

11 studies involving 97,428 patients were analyzed in a systematic review and meta-analysis. The work, authored by Ping Wei and last updated in June 2026, investigates patient-related risk factors for surgical site infection and recurrence after abdominal wall hernia repair. It calculates pooled odds ratios and prediction intervals for factors like diabetes, obesity, and ASA classification.

Use Cases

• [Training risk prediction models] based on the identified associations between patient comorbidities and surgical outcomes.
• [Validating clinical assumptions] based on the meta-analysis results for factors like gender, obesity, and diabetes.
• [Benchmarking clinical heterogeneity] based on the reported wide 95% prediction intervals across surgical settings.
• [Informing perioperative management guidelines] based on the systematic review's conclusions about inconsistent predictors.

Strengths

• Follows PRISMA 2020 and AMSTAR 2 guidelines for systematic review methodology.
• Analyzes data from 97,428 patients aggregated from 11 studies.
• Reports specific statistical metrics including pooled odds ratios, confidence intervals, and 95% prediction intervals.

Limitations

• The underlying data is a 15.6 KB DOCX file, suggesting the dataset is a summary table or manuscript rather than raw patient-level data.
• Column-level documentation is absent; field semantics must be inferred from the description.
• Row count is unknown, which may limit suitability assessment for direct ML training.
