Abstract
RegOBJECTIVES: This study investigated the status quo of systematic reviews published in major journals in Korea from the perspective of protocol registration and adopting the grading of recommendation, assessment, development and evaluation (GRADE) system.
METHODS
We examined systematic reviews published in Korea’s top 15 medical journals from 2018 to 2021. Teams of 2 reviewers assessed the studies’ eligibility criteria and extracted data independently and in duplicate. We collected information on study characteristics, protocol registration, and GRADE use of the included reviews, and reviewed the “Instructions for Authors” of the selected journals to assess any guidance related to systematic reviews.
RESULTS
Out of the 126 identified reviews, 18 (14.3%) reported that they registered or published their protocol. Only 5 (4.0%) rated the certainty of evidence; and all 5 used the GRADE system. Only 6 of 15 journals mentioned systematic reviews in their “Instructions for Authors.” Six journals endorsed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework for systematic review reporting (2 mandatory, 3 recommended, and 1 unclear). None of the journals included mentioned protocol registration or certainty of evidence in their authors’ guidelines.
CONCLUSIONS
Overall, the proportion of systematic reviews that had prior protocol registration or used the GRADE approach to rate the certainty of evidence was very low. Our study highlights the need for adherence to systematic review standards in medical journals in Korea, including prior protocol registration and certainty of evidence assessment. Our review will help improve the quality of systematic reviews in Korea.

한국 의학 저널에서 계획서를 사전에 등록하거나 근거의 확실성을 평가하기 위해 GRADE 접근 방식을 사용한 체계적 문헌고찰의 분율은 낮았다. 우리의 연구는 계획서 등록 및 근거의 확실성 평가를 포함하여 체계적 문헌고찰의 방법론적 표준 준수의 필요성을 강조한다.

Abstract
OBJECTIVES
To conduct a systematic review of coronavirus disease 2019 (COVID-19)-related biosafety guidelines for dental clinical practice in the early stage of the pandemic, focusing on quality assessment.
METHODS
Electronic (via PubMed, Scopus, Web of Science, Latin American and Caribbean Health Sciences Literature database, Brazilian Library in Dentistry, and Cochrane Library) and gray literature searches were performed for documents published up to May 12, 2020. Guidelines updated until April 17, 2021 were identified. Documents were included as guidelines if they (1) consisted of a set of statements, directions, or principles presenting current or future rules or policy; (2) were developed by government agencies, institutions, organizations, or expert panels; and (3) were related to the general conduct of healthcare activities rather a particular condition. Two researchers, using the Appraisal of Guidelines for Research & Evaluation II, independently extracted the recommendations and evaluated the quality of the guidelines.
RESULTS
Twenty-seven documents from 19 countries were included in the review. These documents presented 122 recommendations related to (1) professional biosafety; (2) patients’/companions’ safety; (3) the organization and biosafety of the physical dental facility environment; and (4) the work process in dental care. Overall, the scientific quality of the guidelines was considered low. Some recommendations presented in these guidelines would require further research to establish their effectiveness.
CONCLUSIONS
We found a wide variety of biosafety guidelines for dental practice regarding COVID-19 in the early months of the pandemic, but their quality was low. Biosafety recommendations should be frequently updated.
Summary
Korean summary
Key Message
Despite the wide variety of biosafety guidelines for dental practice regarding COVID-19 in the early months of the pandemic, their quality was low. These findings demonstrate the need for more guidelines for dental practice with more high-quality evidence, focusing on clarification of the strictness of development, financing, conflicts of interest, and applicability. Guidelines with high scientific quality are essential for the formation of a robust scientific consensus facilitating the ability to offer safer and more reliable procedures in the pandemic context.

Abstract
Evidence-based public health (EBPH) is defined as public health decision-making based on current best evidence. Debates about the latent tuberculosis infection control program suggested by the Korea Centers for Disease Control and Prevention in 2017 highlight the need to promote EBPH. Three strategies have been proposed, including providing necessary evidence by evaluating policy-evidence gaps; delivering high-quality, relevant, and timely evidence by conducting systematic reviews and adapting public health guidelines; and making value-driven decisions by training and educating public health policymakers.

Abstract
The Korea Centers for Diseases Control and Prevention (KCDC) has announced a control program against latent Mycobacterium tuberculosis infection (LTBI), for a “TB-safe country” this year with the goal of a “TB-free Korea” by 2025. The program includes high school students as one target group; however, some school health teachers and parents have expressed their opposition to this. The 2015 World Health Organization guidelines do not recommend inclusion of asymptomatic high school students in LTBI control programs. Based on this guideline, the KCDC should consider excluding this population from the program.

Abstract
The Consolidated Standards of Reporting Trials (CONSORT) 2010 Statement, updated in March 2010, includes a 25-item checklist and flow diagram. Adherence to this statement is a minimum requirement for the complete, clear, and transparent reporting of randomized trials. We translated the CONSORT 2010 Statement into Korean to promote the widespread adherence to CONSORT in South Korea and to facilitate the adoption of complete, clear, and transparent reporting. The Korean version of the CONSORT is available at http://www.e-epih.org/.

Abstract
The gap between nationwide recommendations of cancer screening and the related evidences obtained from Korean adults should be filled. Estimation of the mean sojourn time (MST) in a specific cancer is important to determine the intervals of subsequent screening. This author arranged the methods for calculating MST into 5 categories based on the parameters used. Under the legal barrier for protection of individual privacy and confidentiality in a Korean academic situation, the methods involving the use of transition rates or prevalence/incidence ratio would be applicable among these methods.
