Summary
The quality of surgical meta-analyses is suboptimal. First author experience and journal ranking are key factors, with preregistration potentially improving quality.
Area of Science:
- Medical Research
- Surgical Innovation
- Evidence-Based Medicine
Background:
- Surgical meta-analyses are crucial for evidence-based practice.
- Assessing the quality of these studies is vital for reliable conclusions.
- Previous assessments have not focused specifically on surgical meta-analyses.
Purpose of the Study:
- To evaluate the quality of surgical meta-analyses published in 2013.
- To identify factors predicting higher reporting and methodological quality.
Main Methods:
- Systematic search of PubMed and EMBASE for surgical meta-analyses from 2013.
- Quality assessment using PRISMA (reporting) and AMSTAR (methodology) checklists.
- Univariate and multivariate analyses to identify predictive factors.
Main Results:
- 197 meta-analyses were included, showing suboptimal adherence to quality standards.
- Higher reporting and methodological quality were linked to authors with prior meta-analysis experience.
- Publication in higher-ranked journals (Q1) and author origin (non-Asia) were also associated with better quality.
- Preregistration of studies was independently associated with superior quality.
Conclusions:
- Surgical meta-analyses exhibit room for quality improvement.
- Author experience and journal impact factor are significant predictors of quality.
- Preregistration is a promising strategy to enhance the quality of future meta-analyses.

Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...
