    SciScore for 10.1101/2022.03.02.22271759: (What is this?)

    Please note, not all rigor criteria are appropriate for all manuscripts.

    Table 1: Rigor

    EthicsField Sample Permit: This study was a prospective observational study and carried out on an opt-out basis, with relevant disclosures about the study on the prefectural website and informational posters displayed at each institution.
    Sex as a biological variablenot detected.
    Randomizationnot detected.
    Blindingnot detected.
    Power AnalysisSample size calculation: We defined the sample size for each study period to ensure the precision of an estimate.

    Table 2: Resources

    No key resources detected.

    Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study has limitations. As with other serological studies, our current study is not entirely free of selection bias. The age distribution of the general population and that of healthcare-seeking patients at emergency departments should be quite different. Indeed, the age distribution of participants in the current analysis was skewed towards older people, potentially impacting the overall estimates of seroprevalence. Furthermore, emergency outpatients may not accurately represent the local population in terms of the risk of exposure to COVID-19 and preventive behaviors, including the uptake of the vaccine. This “unrepresentativeness” may be more prominent in secondary care hospitals, where disease severity is high. The survey period differed somewhat among the six facilities. This may have had some effects on the results.

    Results from TrialIdentifier: No clinical trial numbers were referenced.

    Results from Barzooka: We did not find any issues relating to the usage of bar graphs.

    Results from JetFighter: We did not find any issues relating to colormaps.

    Results from rtransparent:
    • Thank you for including a conflict of interest statement. Authors are encouraged to include this statement when submitting to a journal.
    • Thank you for including a funding statement. Authors are encouraged to include this statement when submitting to a journal.

    Results from scite Reference Check: We found no unreliable references.

    About SciScore

    SciScore is an automated tool that is designed to assist expert reviewers by finding and presenting formulaic information scattered throughout a paper in a standard, easy to digest format. SciScore checks for the presence and correctness of RRIDs (research resource identifiers), and for rigor criteria such as sex and investigator blinding. For details on the theoretical underpinning of rigor criteria and the tools shown here, including references cited, please follow this link.
