Supplementary file 1_Optimal drain position after evacuation of chronic subdural hematomas

A systematic review and network meta-analysis of 14 articles comprising 4,161 patients compares the efficacy of three drain placement locations for chronic subdural hematoma. The analysis, registered in PROSPERO (CRD42024587692), was conducted by Ningyu Wei and published on figshare in 2026. It evaluates recurrence rates and mortality associated with subdural, subperiosteal, and subgaleal drains.

Use Cases

• Compare the efficacy of different surgical drain placements based on recurrence rate and mortality outcomes.
• Inform clinical decision-making for chronic subdural hematoma treatment based on network meta-analysis rankings.
• Support the design of future clinical studies by identifying the most promising drainage techniques.
• Update clinical guidelines with synthesized evidence from multiple studies on drain placement.

Strengths

• Analysis is based on 14 articles and 4,161 patient records, providing a substantial evidence base.
• Employs network meta-analysis methodology, allowing for comparative ranking of multiple interventions.
• Registered in the PROSPERO database (ID: CRD42024587692), indicating adherence to systematic review protocols.
• Explicitly evaluates two distinct outcome measures: recurrence rate and mortality.

Limitations

• The dataset is a 19.2 KB document file; the underlying patient-level data is not provided.
• Column-level documentation is absent; field semantics must be inferred after download.
• The analysis is limited to studies published up to February 14, 2026; newer evidence is not included.
