  1. SciScore for 10.1101/2020.05.15.098079: (What is this?)

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

    Table 1: Rigor

    Institutional Review Board StatementIACUC: All of the experiments were performed according to National Institutes of Health and United States Department of Agriculture guidelines using experimental protocols approved by the Office of Research Project Protections, Institutional Animal Care and Use Committee (IACUC) at UTMB.
    Randomizationnot detected.
    Blindingnot detected.
    Power Analysisnot detected.
    Sex as a biological variableAnimals: Six- to eight-week-old, female Balb/c mice were purchased from Charles River (Wilmington, MA, USA), and housed in an approved biosafety level 3 animal facility at the University of Texas Medical Branch (UTMB) at Galveston, Texas.
    Cell Line Authenticationnot detected.

    Antibodies
    SentencesResources
    After blocking and then incubating with serially diluted mouse sera, bound IgG antibody was detected using HRP-conjugated anti-mouse IgG (1:2000), followed by the same protocol as described [18, 19, 24].
    anti-mouse IgG
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    The plates were mixed well and cultured at room temperature for 1 h before transferring 100 μl of the immune serum-virus mixtures into designated wells of confluent Vero E6 cells grown in 96-well microtiter plates.
    Vero E6
    suggested: None
    Experimental Models: Organisms/Strains
    SentencesResources
    Animals: Six- to eight-week-old, female Balb/c mice were purchased from Charles River (Wilmington, MA, USA), and housed in an approved biosafety level 3 animal facility at the University of Texas Medical Branch (UTMB) at Galveston, Texas.

    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.

    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.
