    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    It remains possible that our and other published studies reporting declining sero-positivity over time were confounded by assay-related detection weaknesses, however all were performed using high sensitivity and specificity laboratory methods in current clinical use. Another possibility is that sustained SARS-CoV-2 antibody production is dependent on a number of factors including the dose of virus received, host genetics including immune system genotype and phenotype, and the strain of virus present in that geographic location. Interestingly, the mean time of 68.5 days from symptom resolution to study antibody testing suggests that we may have missed many participants who could have been asymptomatic but infected and whose SARS-CoV-2 antibody levels had decreased to sero-negative levels before we commenced sample collection. Our finding over the 28-day study period that 2 previously asymptomatic sero-positive participants lost their previously detectable IgG antibodies against the N-antigen whilst developing detectable IgG antibodies against the S-antigen is novel. This suggests an evolving humoral immune response in both participants, which was also noted in other day 1 sero-positive participants who manifested increased levels of anti-SARS-CoV-2 antibodies on day 28. IgG antibodies targeting SARS-COV-2 S-antigen have been reported to elicit both neutralising29,30 and non-neutralising responses.31 Additionally, N-antigen exposure has been reported to elicit a strong and viab...

    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.
