Quality of Systematic Reviews in Dental Journals Published from India: A Methodological Review

Abstract

AbstractBackgroundEvidence-based medicine (EBM) is a crucial aspect of modern medical practice, emphasizing the use of the best available evidence to inform clinical decision-making. Systematic reviews (SRs) play a key role in EBM by integrating and evaluating findings from multiple studies. However, the methodological quality of SRs can vary, and assessing their quality is essential for accurate interpretation and application of the findings.MethodsThis study aims to analyze the methodological quality of SRs published in dentistry journals from India between 2015 and 2020. A comprehensive search was conducted, resulting in the inclusion of 130 SRs from 21 journals.ResultsThe findings reveal several discrepancies in the methodological quality of the included SRs. Only a small percentage of SRs were registered in the PROSPERO registry, and adherence to PRISMA guidelines was limited. The majority of SRs did not assess scientific quality, such as risk of bias and publication bias, adequately. Furthermore, the study highlights a lack of awareness and support for conducting high-quality SRs, including limited funding and insufficient utilization of standardized guidelines.ConclusionThe authors suggest that increasing awareness among researchers, editors, and funding agencies, as well as adopting standardized guidelines and protocols, can improve the quality and quantity of SRs produced in India. Overall, this study emphasizes the need to enhance the methodological rigor of SRs in dentistry to ensure reliable evidence for clinical decision-making.
