Abstract
Abstract
Background: Comprehensive inclusion of evidence is crucial for conducting systematic reviews (SRs), and including studies published in language other than English (LOTE) is an integral aspect of this process. However, the inclusion of LOTE in SRs remains limited, and there is a lack of understanding regarding appropriate approaches to accomplish this. An encouraging trend in recent years is the increasing number of SRs attempting to include LOTE. These endeavors present us with an opportunity to devel into this topic further.
Objectives: The aims of this study are to identify JBI SRs including LOTE and to examine their processes, justifications, and approaches for the inclusion of LOTE.
Methods: The dataset from JBI Evidence Synthesis was used to identify all SRs that either intended to or did include LOTE, published between 2018 and 2022. Screening and data extraction were independently conducted by two reviewers. Data related to LOTE were descriptively analyzed and synthesized narratively.
Results: The anticipated results will encompass the frequencies of inclusion/exclusion of LOTE throughout the SRs process, along with their justifications. Additionally, the search strategies, the analytical approaches, the reporting formats, and the associated limitations of LOTE will also be summarized. In particular, the methods used to maintain credibility, transferability, dependability, and confirmability of cross-language qualitative synthesis will be highlighted.
Conclusions: While various approaches exist to address challenges in managing LOTE in SRs, these methods have not undergone systematic testing, resulting in a lack of universal recognition. Authors of SRs are encouraged to practice and critically consider existing approaches or develop new ones to effectively utilize LOTE.
The findings of this study will broaden the understanding of the current status of including LOTE in SRs, while also providing insights for the establishment of future standards for their better inclusion in SRs.
