  1. SciScore for 10.1101/2021.12.20.21268096: (What is this?)

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

    8 For the calculation of case, hospitalization, and death rates, data were smoothed using a 7-day moving average in STATA version 16.1; weekly rates are unsmoothed.

    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:
    Limitations of our study include the use of publically available data on Covid-19 morbidity and mortality that was collated in surveillance systems and could have changed over time, which could affect comparisons across the four waves. DATCOV surveillance does not distinguish between SARS-CoV-2 cases hospitalized for Covid-19 and those admitted for other illness who coincidentally test positive for SARS-CoV-2 on routine screening. Nevertheless, these systems are unlikely to have changed since the Delta-dominant third wave. Another limitation is that the current wave is only in its fourth week at data cut-off, although the 7-day rolling average of case rate has plateaued and is on a downward trend. Also, our contention that cell-mediated immunity primarily due to natural infection, with or without Covid-19 vaccination, is resulting in the uncoupling of case rates and severe disease remains to be investigated. In particular, the extent to which the polyepitopic T-cell responses induced by vaccination against the spike-protein and the even more diverse polyepitopic T-cell response stimulated by natural infection, with or without vaccination, warrant investigation. As there may be a 1-2 week lag between the surge in SARS-CoV-2 infections and severe Covid-19 cases, monitoring is ongoing to determine whether the uncoupling of case rate and rate of severe illness remains during the current Omicron-dominant wave. If so, we believe it may herald a turning point in the Covid-19 pandemi...

    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.
