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

    Table 1: Rigor

    Institutional Review Board StatementIRB: All data were anonymised, and the study was approved by the Ethics Committee of Hospital 12 de Octubre Hospital in April 3th, with ref N° CEIm: 20/160.
    Randomizationnot detected.
    BlindingThe control cohort was assembled from the Microbiology databases of the participating centres matched on a 1:1 basis with the rheumatic cohort on the date of COVID-19 diagnosis (“index date”), sex, and age, and blinded to outcome or other variables.
    Power Analysisnot detected.
    Sex as a biological variableFactors studied in relation to the outcome were those common to all COVID patients, such as age (with a cut-off at 60 years), male sex, cardiovascular disease, obesity, diabetes, hypertension, and lung disease.

    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:
    Whether specific diagnostics among these groups may have a different risk cannot be ruled-out due to statistical power limitation. In our previous prevalence analysis, hospital cases were more prevalent among SpA but not RA or PSA groups, and in AI/IMID groups but not SLE patients compared to the reference population [8]. Further analyses would be needed to evaluate the severity of specific rheumatic diseases. Concerning previous use of therapies by rheumatic patients, the use of glucocorticoids was associated with poorer outcome by bivariable analysis, whereas no substantial risk was detected neither for traditional immunosuppressants nor csDMARDS (methothrexate and leflunomide), nor for bDMARD (mostly anti-TNF-α). Interestingly, the use of ts/bDMARD was associated in the bivariable with lower odds of complications. They did not make it into the final models probably because of the collinearity with other variables and not being the full rheumatic sample included, thus encountering problems of statistical power. The potential therapeutic effect of anti-cytokine biologicals and Jakinibs on COVID-19 is being tested through numerous observational and randomised trials [17]. Since most of these drugs have long-lived pharmacological or immunological effects, a protective effect could hypothetically exist after SARS-CoV-2 infection. In our previous analysis of the prevalence of hospital PCR+ cases in rheumatic patients and the general population, a higher prevalence was observed i...

    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.
