Established in September 2019 by Robin Vernooij and Chris Champion, the ECPN was inspired by similar early career researcher groups in scientific associations. Cochrane received many inquiries from young researchers eager to engage with the activities, highlighting a growing demand for such a network.&lt;/p&gt;&lt;p&gt;Cochrane's contributors come from varied backgrounds and cultures, including researchers, health sciences students, language translators, and other volunteers, all united in their commitment to supporting global healthcare initiatives [&lt;span&gt;2&lt;/span&gt;]. In line with Cochrane's mission to highlight the contributions of the next generation, Cochrane launched the “30 Under 30” initiative, inviting 30 young researchers with diverse professional backgrounds such as nurses, doctors, dentists, physiotherapists, biologists, psychologists, and journalists to join the series and tell their Cochrane Story. To build on the success of this initiative, Vernooij proposed formalizing this group into a network, which was well received as the idea aligned perfectly with the Cochrane membership strategy. Consequently, all participants in the “30 Under 30” series were invited to become the first members of the ECPN [&lt;span&gt;2&lt;/span&gt;]. The ECPN was due to be launched in Santiago, Chile at the 2019 Cochrane Colloquium, themed “Embracing Diversity,” but due to the cancellation of the event, it was ultimately launched online later in 2019.&lt;/p&gt;&lt;p&gt;The ECPN now plays a crucial role in promoting professional development, international networking, collaboration, and leadership within the Cochrane community, ensuring that the voices of early career professionals (ECP) are heard, and their potential maximized [&lt;span&gt;1&lt;/span&gt;]. The objective of this commentary is to provide a comprehensive overview of the ECPN in Cochrane, with the aim of raising awareness and enhancing the visibility of the network within the Cochrane and scientific community.&lt;/p&gt;&lt;p&gt;The ECPN is focused on expanding our international network and fostering closer collaboration with other groups, such as the Campbell Collaboration, the Joanna Briggs Institute, Sense about Science, and the Cochrane US mentoring program [&lt;span&gt;3&lt;/span&gt;].

This tool provides a systematic approach to appraise the validity of these studies. Our process may guide others in the development of appraisal tools in areas where they are needed. Given the relationship between clinical laboratory studies and the development of medical treatments, further development of this risk of bias tool is important for evidence-based healthcare and research.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100286,"journal":{"name":"Cochrane Evidence Synthesis and Methods","volume":"2 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cesm.12098","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141967894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A systematic review and evidence and gap map","authors":"Mary Fredlund,&nbsp;Morwenna Rogers,&nbsp;Noreen Orr,&nbsp;Dylan Kneale,&nbsp;Kate Allen,&nbsp;Jo Thompson Coon","doi":"10.1002/cesm.12096","DOIUrl":"https://doi.org/10.1002/cesm.12096","url":null,"abstract":"<div>\u0000 \u0000 \u0000 <section>\u0000 \u0000 <h3> Introduction</h3>\u0000 \u0000 <p>Clarity on the characteristics of methods used to produce evidence and gap maps (EGMs) will highlight areas where method development is needed to ensure these increasingly produced tools are made following best practice to assure their quality and utility. This paper aims to describe the range, nature and variability of key methodological characteristics of studies publishing EGMs.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>We followed a protocol, written a-prior and informed by PRISMA and MECCIR guidelines for undertaking systematic reviews. We searched nine data bases, from 2010, for studies across any discipline that included details of their methods used to produce an EGM. Search results were screened by two reviewers independently and the subsequent data was extracted and managed according to predefined criteria. We mapped these together with the year of publication and the area of research as the two primary dimensions. We followed established methods for mapping the evidence, including the process of developing the map framework and the filters for our interactive map. We sought input and involvement from stakeholders during this process.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>We found 145 studies from nine distinct research areas, with health research accounting for 67%. There were 11 map designs found, of these bubble plots were the most common design, before 2019, since then it has been a matrix map design. Stakeholders were involved in 47.7% of studies, 48.35% of studies stated finding gaps was an aim of their work, 42% reported publishing or registering a protocol and only 9.39% of studies mentioned a plan to update their evidence maps/EGMs.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Discussion/Conclusion</h3>\u0000 \u0000 <p>Key areas of methodological development relate to: the involvement of stakeholders, the conceptualization of gaps and the practices for updating maps. The issues of ambiguity in terminology, the flexibility of visualizations of the data and the lack of reporting detail were other aspects that needs further consideration in studies producing an EGM.</p>\u0000 </section>\u0000 </div>","PeriodicalId":100286,"journal":{"name":"Cochrane Evidence Synthesis and Methods","volume":"2 8","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cesm.12096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141967325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
