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

    Table 1: Rigor

    Institutional Review Board StatementIRB: The study was approved by the Ethics Committee of Clinical Hospital of the School of Medicine of the University of Sao Paulo and by the Ethics Committee of Ibirapuera Field Hospital.
    Consent: The participants provided written informed consent before being enrolled in the study (approval number: 30959620.4.0000.0068).
    RandomizationStudy design: This is a prospective, cohort study nested within a multicenter, randomized controlled trial designed to test the safety and efficacy of vitamin D3 supplementation in hospitalized patients with severe COVID-19 (ClinicalTrials.gov Identifier: NCT04449718), conducted between June 2, 2020 and October 7, 2020.

    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:
    The main limitations of this study involve its observational nature, which hampers causative relationships; the small sample size, which increases the chances of type 2 errors, particularly considering the low incidence for the secondary outcomes; the use of a questionnaire to assess physical activity, which is prone to recall bias, overreporting, and limited time frame of evaluation (i.e., 1 year); and the lack of patients’ follow-up after the hospital discharge. In conclusion, among hospitalized patients with COVID-19, physical activity did not associate with hospital length of stay or any other clinically relevant outcomes. These findings, which needs further replication in larger cohorts, suggest that previous physical activity levels may not change the prognosis of severe COVID-19.

    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.
