Data, Analytic Methods (Code), and Research Materials Transparency

The policy of the Journal of Laryngology and Otology is to publish papers where authors indicate whether the data used to conduct the research will be made available to any researcher for purposes of reproducing the results or replicating the procedure. The Journal also encourages the inclusion of analytic methods and research materials used to conduct the research.

• Authors must, in acknowledgements or the first footnote, indicate if they will or will not make their data available to other researchers.
• If an author agrees to make data available, the author must specify where that material will be available.

Design and Analysis Transparency

The policy of the Journal of Laryngology and Otology is to publish papers where authors follow standards for disclosing key aspects of the research design and data analysis. Authors must review the standards available for many research applications from http://equator-network.org/ and use those that are relevant for the reported research applications. At manuscript submission, authors must confirm that they reviewed the standards, report whether any standards were relevant for the research application, and confirm that they followed those standards in the manuscript.

Preregistration of Studies

The policy of the Journal of Laryngology and Otology is to publish papers where authors indicate whether the conducted research was preregistered in an independent, institutional registry (e.g. http://clinicaltrials.gov/, http://socialscienceregistry.org/, http://openscienceframework.org/, http://egap.org/design-registration/, http://ridie.3ieimpact.org/). Preregistration of studies involves registering the study design, variables, and treatment conditions prior to conducting the research.

• Authors must, in acknowledgements or the first footnote, indicate if they did or did not preregister the research in an independent, institutional registry.
• If an author did preregister the research, the author must confirm that the study was registered prior to conducting the research with links to the time-stamped preregistrations at the institutional registry, and that the preregistration adheres to the disclosure requirements of the institutional registry or those required for the preregistered badge maintained by the Center for Open Science.

Preregistration of Analysis Plans

The policy of the Journal of Laryngology and Otology is to publish papers where authors indicate whether or not the conducted research was preregistered with an analysis plan in an independent, institutional registry (e.g. http://clinicaltrials.gov/, http://socialscienceregistry.org/, http://openscienceframework.org/, http://egap.org/design-registration/, http://ridie.3ieimpact.org/). Preregistration of studies involves registering the study design, variables, and treatment conditions. Including an analysis plan involves specification of sequence of analyses of the statistical model that will be reported.

• Authors must, in acknowledgements or the first footnote, indicate if they did or did not preregister the research with or without an analysis plan in an independent, institutional registry.
• If an author did preregister the research with an analysis plan, the author must:
  • Confirm in the text that the study was registered prior to conducting the research with links to the time-stamped preregistrations at the institutional registry, and that the preregistration adheres to the disclosure requirements of the institutional registry or those required for the preregistered badge with analysis plans maintained by the Center for Open Science.
  • Report all pre-registered analyses in the text, or, if there were changes in the analysis plan following preregistration, those changes must be disclosed with explanation of the changes.
  • Clearly distinguish in text analyses that were preregistered from those that were not, such as having separate sections in the results for confirmatory and exploratory analyses.
