    SARS-CoV-2 RBD IgG immunoassay: IgG antibodies binding to SARS-CoV-2 RBD made in Sf9 cells infected with recombinant baculoviruses (Invitrogen, CA, USA) were measured by an enzyme-linked immunosorbent assay (ELISA) as previously described [23].

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    The current study has several limitations that must be acknowledged; predominantly, the reduced cohort size. Second, T-cell immunity analyses were conducted at a single time point. We cannot rule out that detectability of the two SARS-CoV-2-reactive T cells by the immunoassay used herein may fluctuate over time. Moreover, no whole blood specimens drawn at the time of patient hospitalization were available for T-cell immunity assessment. Third, T cells and antibodies targeting other antigen specificities, which may afford protection against SARS-CoV-2, were not evaluated. Fourth, T-cell functionalities other than IFN-γ production upon antigenic stimulation were not explored. Fifth, we cannot be certain whether our whole blood T-cell immunoassay might be less sensitive than others using fresh or cryopreserved isolated PBMCs. Sixth, taking serum peak levels of IL-6, Dimer-D and ferritin during the first 15 days after symptoms onset is an admittedly arbitrary time point for analyses which may not have captured the true net state of systemic inflammation generated shortly after SARS-CoV-2 infection. In summary, we have shown that a relatively low number of subjects who developed severe forms of COVID-19 had detectable SARS-CoV-2-S1/M IFNγ CD4+ and CD8+ T cells at medium term after clinical diagnosis (up to 6 months), particularly those with concurrent comorbidities. Our data also indicated that serum levels of RBD-specific IgGs decline over time, becoming undetectable in some pati...

    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.
