Which reporting guideline is commonly used for cohort studies?

• A. CONSORT guidelines
• B. PRISMA guidelines
• C. CARE guidelines
• D. STROBE guidelines

Answer: (D)

Reporting guidelines for observational studies, including cohort studies, are best served by the STROBE guidelines. STROBE, which stands for Strengthening the Reporting of Observational Studies in Epidemiology, provides a focused checklist for how the study is designed, conducted, analyzed, and interpreted, ensuring transparency and completeness in reporting. Because cohort studies are a type of observational study, STROBE specifically addresses the key elements such as participant selection, measurement of exposures and outcomes, handling of bias and confounding, and the statistical methods used—making it the most appropriate and commonly used guideline in this context.

Other guidelines target different study designs: CONSORT is for randomized controlled trials, PRISMA is for systematic reviews and meta-analyses, and CARE is for case reports. Using STROBE helps readers assess the quality and reproducibility of a cohort study by providing a clear structure for reporting all essential aspects.
