Abstract
The objective of clinical trials is to answer about intervention in the real-world, for which they must be properly designed and executed by presenting the results reliably with the findings and in a clear way. OBJECTIVES: To identify the risk of bias in clinical trials about interventions for diabetic retinopathy and/or diabetic macular edema from Cochrane systematic reviews. METHODS: A sensitive search strategy was designed to search Cochrane systematic reviews of interventions in diabetic retinopathy and diabetic macular edema. The assessment of the risk of bias was captured as presented by the author. FINDINGS: We found eight SR and one meta-analysis network totaling 116 randomized clinical trials. Our sample revealed that among the domains randomization, allocation secret, masking of participants and personnel, incomplete outcomes, selective outcomes and others, the risk of bias assessed as low ranged from 30.4 to 49.1%; unclear risk between 22 to 56% and high risk from 1 to 21.7%. CONCLUSIONS: The risk of bias in diabetic retinopathy randomized clinical trials exists in high frequency and the reader must be aware of it.
期刊介绍:
The International Journal of Evidence-Based Healthcare is the official journal of the Joanna Briggs Institute. It is a fully refereed journal that publishes manuscripts relating to evidence-based medicine and evidence-based practice. It publishes papers containing reliable evidence to assist health professionals in their evaluation and decision-making, and to inform health professionals, students and researchers of outcomes, debates and developments in evidence-based medicine and healthcare.
The journal provides a unique home for publication of systematic reviews (quantitative, qualitative, mixed methods, economic, scoping and prevalence) and implementation projects including the synthesis, transfer and utilisation of evidence in clinical practice. Original scholarly work relating to the synthesis (translation science), transfer (distribution) and utilization (implementation science and evaluation) of evidence to inform multidisciplinary healthcare practice is considered for publication. The journal also publishes original scholarly commentary pieces relating to the generation and synthesis of evidence for practice and quality improvement, the use and evaluation of evidence in practice, and the process of conducting systematic reviews (methodology) which covers quantitative, qualitative, mixed methods, economic, scoping and prevalence methods. In addition, the journal’s content includes implementation projects including the transfer and utilisation of evidence in clinical practice as well as providing a forum for the debate of issues surrounding evidence-based healthcare.
