    GraphPad Prism
    suggested: (GraphPad Prism, RRID:SCR_002798)
    Computational analysis: The amino acid locations on the RBD that affected nAb potency were modeled with PyMOL molecular graphics system (version 1.7.4; Schrödinger, LLC) using the Protein Data Bank (PDB) entries 6ZOZ for the closed conformation and 7A98 for the open conformation.
    suggested: (PyMOL, RRID:SCR_000305)

    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:
    Finally, the safety and simplicity of pseudovirus neutralization assays offer many advantages for identifying MOCs and screening antibody therapeutics and vaccinee sera, but such assays have limitations. Pseudoviruses do not completely mimic authentic SARS-CoV-2 or virus entry conditions in vivo. In our nAb screens, we found that two antibodies that bind outside of the receptor binding motif could only partially neutralize (< 80%) pseudoviruses bearing WT Spike (data not shown). This inability to achieve complete neutralization by some nAbs has been observed by others using authentic SARS-CoV-2 (54, 68) and may be due to use of engineered target cells that permit efficient virus entry or heterogeneous glycosylation of Spike that affects an antibody epitope. Neutralization assays also cannot measure the potential protective activity afforded by nAb Fc effector functions. To address the limitations of any single assay, several consortia have formed to integrate findings from animal models and in vitro assays involving a variety of formats to inform the development of potent antibody therapeutics and other medical countermeasure that will remain potent against emerging variants.

    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.

    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.
