[1] This extension of the traditional PRISMA checklist was needed to address the deficient reporting of diagnostic test accuracy (DTA) studies. [2]<\/span><\/p>\n<p><span style=\"font-weight: 400\">Participating in this collective effort shed light on the dire need for an evaluation of the completeness of reporting of published DTA systematic reviews to help identify areas of deficiencies and strategies to improve transparent reporting. This inspired the main project of my master\u2019s thesis, in which 100 reviews were included. [3] On average 71% of the items in PRISMA-DTA were reported, with the most frequently reported items pertaining to data-collection and statistical methods. Many study reports failed to mention whether they had been registered in a study registry, others lacked details regarding characteristics of the included studies, and the definitions used in data extraction, data synthesis, and results-synthesis. Additionally, we identified five items that were inadequately reported in our sample; these were items related to funding information, characteristics of included studies, strengths and limitations of the review, and the applicability of the findings. Since it is possible that the incomplete reporting of key items was due to a limited understanding of the arguments for including these items in the report, drafting an explanation and elaboration document became our new goal, as it would further assist researchers undertaking DTA systematic reviews to better grasp the rationale for reporting each item and provides them with examples of optimal practices and act as a pedagogical resource.<\/span><\/p>\n<p><span style=\"font-weight: 400\">Insufficient reporting in DTA research could prevent stakeholders who place reliance on DTA systematic reviews from critically evaluating the quality of evidence and may consequently promote misallocation of resources. With the support of the PRISMA-DTA group, we wanted to highlight the rationale for transparent reporting in the evaluation of the review through providing examples and explanations. For instance, failure to report the intended use and clinical role of the index test (item D1) could prevent stakeholders and clinicians from clearly identifying whether the test is aimed for diagnostic, screening, staging or other purposes. Furthermore, reports that fail to provide the search strategy used to identify studies for inclusion (item 8) not only impede the successful replicability of the review, but also limit the readers\u2019 ability to evaluate the comprehensiveness of the review.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400\">Improving reporting practices requires efforts to guide authors and stakeholders forward, while providing them with all the fundamental resources and guidance to succeed. <a href=\"https:\/\/www.bmj.com\/content\/370\/bmj.m2632\">This explanation and elaboration document<\/a>, along with the PRISMA-DTA checklist are the first steps towards this goal, but additional steps will include an explanation and elaboration document for the PRISMA-DTA for Abstracts <\/span><a href=\"https:\/\/www.equator-network.org\/reporting-guidelines\/prisma-abstracts\/\"><span style=\"font-weight: 400\">checklist<\/span><\/a><span style=\"font-weight: 400\">.<\/span><\/p>\n<p><em><span style=\"font-weight: 400\"><strong>Jean-Paul Salameh<\/strong>, methodologist, Ottawa Hospital Research Institute<\/span><\/em><\/p>\n<p><em><span style=\"font-weight: 400\"><strong>Matthew DF McInnes<\/strong>, <\/span><span class=\"contrib-role\">professor of radiology and epidemiology, Clinical Epidemiology Programme, Ottawa Hospital Research Institute<\/span><\/em><\/p>\n<p><em><span style=\"font-weight: 400\"><strong>David Moher<\/strong>, <\/span><span class=\"contrib-role\">senior scientist, Ottawa Hospital Research Institute Clinical Epidemiology Program<\/span><\/em><\/p>\n<p><em><span style=\"font-weight: 400\"><strong>Brett D Tombs<\/strong>, <\/span><span class=\"contrib-role\">professor of psychology, McGill University, Montr\u00e9al<\/span><\/em><\/p>\n<p><em><strong>Patrick <\/strong><span style=\"font-weight: 400\"><strong>M.
