Observational studies in Cardiovascular and Metabolism (CVM) research in Spanish journals reported less than 60% of STROBE statement items. Deficiencies were most noted in the Methods and Results sections.
Area of Science:
- Biomedical research reporting standards.
- Observational study methodology.
Context:
- Biomedical studies often exhibit reporting deficiencies, necessitating adherence to guidelines like the STROBE statement.
- Assessing adherence to reporting guidelines is crucial for scientific rigor and reproducibility.
Purpose:
- To evaluate the completeness of reporting for observational studies in the Cardiovascular and Metabolism (CVM) therapeutic area.
- To assess adherence to the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) statement in Spanish CVM publications from 2009.
Summary:
- A cross-sectional analysis examined 74 CVM observational studies published in 2009 across 6 Spanish journals.
- Studies, primarily cohort and cross-sectional designs, reported a mean of 20 out of 34 STROBE items (58% compliance).
- Reporting completeness varied by journal, with Gaceta Sanitaria showing higher adherence than Hipertensión.
Impact:
- Spanish CVM observational studies in 2009 showed moderate adherence to STROBE recommendations, with significant deficiencies in Methods and Results sections.
- Findings highlight the need for improved adherence to reporting guidelines to enhance the quality and transparency of published research.
