  1. SciScore for 10.1101/2020.11.30.404905: (What is this?)

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

    Table 1: Rigor

    Institutional Review Board StatementIRB: The collection of patient plasma was approved by the Human Research Protection Office at Washington University in St. Louis (IRB reference number 202007097) and the Institutional Review Board of The Hong Kong University and the Hong Kong Island West Cluster of Hospitals (IRB reference number UW20-169).
    Randomizationnot detected.
    Blindingnot detected.
    Power Analysisnot detected.
    Sex as a biological variablenot detected.
    Cell Line Authenticationnot detected.

    Table 2: Resources

    Antibodies
    SentencesResources
    Following FBS blocking and thorough washing, diluted plasma samples (1:100) were bound for 2 hours, further washed and then detected by an anti – human IgG secondary antibody labelled with HRP (Invitrogen), and absorbance detected at 450nm on a spectrophotometer (Wallac)
    anti – human IgG
    suggested: None
    human
    suggested: None
    Experimental Models: Cell Lines
    SentencesResources
    IFN-β promoter reporter gene assay: HEK-293T cells (5 × 104) were co-transfected using Lipofectamine 2000 with 25 ng of an IFN-β promoter-firefly luciferase reporter plasmid, 25 ng of pRL-TK Renilla luciferase reporter plasmid, and 125, 12.5, and 1.25 ng of the indicated viral protein expression plasmid.
    HEK-293T
    suggested: None
    Software and Algorithms
    SentencesResources
    Fluorescence Polarization Assay (FPA): FPA experiments were performed on a Cytation5 plate reader (BioTek) operating on Gen5 software.
    Gen5
    suggested: (Gen5, RRID:SCR_017317)
    The fluorescence polarization values were then plotted against N concentrations to fit the dissociation constant, KD, using ORIGIN software.
    ORIGIN
    suggested: (Origin, RRID:SCR_014212)

    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.

    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.
