Strengthening the reporting of observational studies in epidemiology

The STROBE (STrengthening the Reporting of OBservational studies in Epidemiology) Statement is a reporting guideline including a checklist of 22 items that are considered essential for good reporting of observational studies. It was published simultaneously in several leading biomedical journals in October and November 2007 and comprises both the checklist{{cite journal | vauthors = von Elm E, Altman DG, Egger M, Pocock SJ, Gøtzsche PC, Vandenbroucke JP | title = The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement: guidelines for reporting observational studies | journal = Epidemiology | volume = 18 | issue = 6 | pages = 800–4 | date = November 2007 | pmid = 18049194 | doi = 10.1097/EDE.0b013e3181577654 | doi-access = free }} and an explanation and elaboration article{{cite journal | vauthors = Vandenbroucke JP, von Elm E, Altman DG, Gøtzsche PC, Mulrow CD, Pocock SJ, Poole C, Schlesselman JJ, Egger M | display-authors = 6 | title = Strengthening the Reporting of Observational Studies in Epidemiology (STROBE): explanation and elaboration | journal = Epidemiology | volume = 18 | issue = 6 | pages = 805–35 | date = November 2007 | pmid = 18049195 | doi = 10.1097/EDE.0b013e3181577511 | s2cid = 44770054 | doi-access = free }} which gives examples of good reporting and provides authors with more guidance on good reporting. It is also referred to in the Uniform Requirements for Manuscripts Submitted to Biomedical Journals established by the International Committee of Medical Journal Editors and is endorsed by hundreds of biomedical journals.{{Cite web|url=https://www.strobe-statement.org/index.php?id=strobe-endorsement|title=STROBE Statement: Endorsement|website=www.strobe-statement.org|access-date=2020-04-29}}

Purpose

The STROBE Statement was developed by the STROBE Initiative, an international collaboration of epidemiologists, methodologists, statisticians, researchers and journal editors with the aim to assist authors when writing up analytical observational studies, to support editors and reviewers when considering such articles for publication, and to help readers when critically appraising published articles. {{cite journal | vauthors = von Elm E, Altman DG, Egger M, Pocock SJ, Gøtzsche PC, Vandenbroucke JP | title = The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) statement: guidelines for reporting observational studies | journal = PLOS Medicine | volume = 4 | issue = 10 | pages = e296 | date = October 2007 | pmid = 17941714 | pmc = 2020495 | doi = 10.1371/journal.pmed.0040296 | doi-access = free }}

Adaptations and future

In 2010, three years after STROBE's publication, the original creators reconvened and deemed an update unnecessary at the time.{{Cite web|url=https://www.strobe-statement.org/index.php?id=strobe-home|title=STROBE Statement: Home|website=www.strobe-statement.org|access-date=2020-04-29}} However, since, calls have supported for the reporting guideline to be updated, similarly to other reporting guidelines (like CONSORT and PRISMA) which have been updated as needed. An assessment of extension content{{cite journal | vauthors = Sharp MK, Hren D, Altman DG | title = The STROBE Extensions: Considerations for Development | journal = Epidemiology | volume = 29 | issue = 6 | pages = e53–e56 | date = November 2018 | pmid = 30052544 | doi = 10.1097/EDE.0000000000000899 | pmc = 7659437 | url = https://zenodo.org/record/3603370 }} as well as a survey of authors of observational studies{{cite journal | vauthors = Sharp MK, Bertizzolo L, Rius R, Wager E, Gómez G, Hren D | title = Using the STROBE statement: survey findings emphasized the role of journals in enforcing reporting guidelines | journal = Journal of Clinical Epidemiology | volume = 116 | pages = 26–35 | date = December 2019 | pmid = 31398440 | doi = 10.1016/j.jclinepi.2019.07.019 | doi-access = free | hdl = 2117/339689 | hdl-access = free }}{{cite journal | vauthors = Sharp MK, Glonti K, Hren D | title = Online survey about the STROBE Statement highlighted divergent views about its content, purpose, and value | journal = Journal of Clinical Epidemiology | date = April 2020 | volume = 123 | pages = 100–106 | pmid = 32259582 | doi = 10.1016/j.jclinepi.2020.03.025 | doi-access = free }} provided several areas to improve upon.

The STROBE Statement checklist is also available to use within a Writing Aid Tool{{cite journal | vauthors = Hawwash D, Sharp MK, Argaw A, Kolsteren P, Lachat C | title = Usefulness of applying research reporting guidelines as Writing Aid software: a crossover randomised controlled trial | journal = BMJ Open | volume = 9 | issue = 11 | pages = e030943 | date = November 2019 | pmid = 31699728 | pmc = 6858139 | doi = 10.1136/bmjopen-2019-030943 }}{{cite web |last=carllachat|title=carllachat/WritingAidTool|website=GitHub|date=2020-01-23|url=https://github.com/carllachat/WritingAidTool|access-date=2020-04-29}} add-in for Microsoft Word that includes the STROBE checklist within the software.

The STROBE Statement has also been adapted as a public, open-source repository for epidemiological research methods and reporting skills for observational studies. Epidemiologists, statisticians, and public health researchers are able to comment and edit the tool to inform future updates of the reporting guideline.{{cite book|last=Sharp|first=Melissa K. | name-list-style = vanc |url= https://bookdown.org/melissaksharp/strobe_eduexpansion/ |title=Strengthening the Reporting of Observational Studies in Epidemiology STROBE (STROBE) Educational Expansion}}
