  1. SciScore for 10.1101/2021.07.22.453309: (What is this?)

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

    Table 1: Rigor

    EthicsIACUC: The experiments with C57BL/6 and IFNAR-/-mice were performed with permission of the Ankara University Ethical Committee for Animal Experiments (06 May 2020, 20120-8-66) in the high containment animal facility (ABSL3+), conducted according to the national regulations on the operation and procedure of animal experiments’ ethics committees (regulation no. 26220, 9 September 2006).
    IRB: The experiments with C57BL/6 and IFNAR-/-mice were performed with permission of the Ankara University Ethical Committee for Animal Experiments (06 May 2020, 20120-8-66) in the high containment animal facility (ABSL3+), conducted according to the national regulations on the operation and procedure of animal experiments’ ethics committees (regulation no. 26220, 9 September 2006).
    Sex as a biological variablenot detected.
    RandomizationA total of 28 IFNAR-/- mice (8-12 weeks) were randomly divided into 6 groups for prophylaxis and contact experiments as well as controls Individuals in the prophylaxis group received intranasal rGRFT and inoculated with SARS-CoV-2 Ank1 after 4 hours.
    Blindingnot detected.
    Power AnalysisThe suspension was sonicated at 30% power for 10 cycles of 15s on/45s off.
    Cell Line Authenticationnot detected.

    SentencesResources
    Then the membrane was incubated in 5% milk in TBS-T containing 1:10000 primary anti-his mouse antibody at 4°C, overnight.
    anti-his
    suggested: None
    Secondary antibody solution containing 1:3000 horseradish peroxidase (HRP) conjugated goat anti-mouse secondary antibody (Abcam ab6789-1 MG) in PBS-T was added to each well and incubated for 1 hour.
    anti-mouse
    suggested: None
    The x6-His peptide present in the recombinant protein was targeted as the control, detected using mouse anti-His antibodies, anti-mouse-IgG-HRP and conjugate and TMB substrate.

    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: An explicit section about the limitations of the techniques employed in this study was not found. We encourage authors to address study limitations.

    Results from TrialIdentifier: No clinical trial numbers were referenced.


    Results from Barzooka: We found bar graphs of continuous data. We recommend replacing bar graphs with more informative graphics, as many different datasets can lead to the same bar graph. The actual data may suggest different conclusions from the summary statistics. For more information, please see Weissgerber et al (2015).


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


    Results from rtransparent:

    • Thank you for including a funding statement. Authors are encouraged to include this statement when submitting to a journal.
    • No protocol registration statement was detected.

    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.
