  1. SciScore for 10.1101/2021.11.21.469172: (What is this?)

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

    Table 1: Rigor

    EthicsField Sample Permit: All animal experiments were approved by the Experimental Animals Committee of SHMC, and all methods were carried out in accordance with relevant guidelines and regulations.
    Sex as a biological variableMice: Female BALB/c mice (6-8 weeks of age) were purchased from Beijing Vital Laboratory Animal Technology Co., Ltd. (Beijing, China) and Shanghai Jiesjie Laboratory Animal Co., Ltd. (Shanghai, China), and were kept in SPF conditions.
    RandomizationAll animal studies were performed with randomized animal selection.
    Blindingnot detected.
    Power Analysisnot detected.

    Recombinant DNA
    SentencesResources
    Peptide pool derived from SARS-CoV-2 Spike protein: The spike receptor-binding domain (RBD) peptide pool (SARS-CoV-2 spike protein 258-518aa) published previously7 was used for the study (Table 1). Immunization: The mice were injected twice, with a two-week interval, via the intramuscular route (i.m.) with 25 μg pGX9501 expressing a synthetic, optimized sequence of the SARS-CoV-2 full-length spike glycoprotein7 and then electroporation was applied with the Cellectro2000 device.

    Six hours later, the percentage of labeled cells in spleens was detected with LSRFortessa flow cytometry (BD) and analyzed by FlowJo (TreeStar).

    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 did not find any issues relating to the usage of bar graphs.


    Results from JetFighter: Please consider improving the rainbow (“jet”) colormap(s) used on page 23. At least one figure is not accessible to readers with colorblindness and/or is not true to the data, i.e. not perceptually uniform.

    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.
