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

    Institutional Review Board StatementIRB: The study was approved by the Local Ethics Committee of the HUS Helsinki University Hospital.
    Consent: Informed consent was obtained from the patients or the next of kin of those critically ill.
    Randomizationnot detected.
    Blindingnot detected.
    Power Analysisnot detected.
    Sex as a biological variableAnemia was defined as hemoglobin < 134 g/l for men and < 117 g/l for women, leukopenia as white blood cells < 3.4 × 109/l and lymphopenia as blood lymphocytes < 1.2 × 109/l and thrombocytopenia as platelet count < 150 × 109/l.

    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Our study had several limitations. The sample size was small, which should be taken into account when interpreting the results. All patients admitted to HUS Jorvi Hospital with COVID-19 or influenza were not eligible; for example they lived outside of the Jorvi Hospital catchment area or did not consent to participate. Elderly patients were underrepresented as patients with pre-existing treatment limitations or not requiring specialized care were admitted to the secondary care Espoo Hospital. The time from symptom onset to hospitalization may not be completely comparable between COVID-19 and influenza patients because, until March, only patients with symptom onset within the last 7 days were included. Furthermore, this study is based on clinical data and no extra laboratory testing or radiological imaging was done in addition to the detection of influenza and SARS-CoV-2 RNA. Consequently, CT scans, coagulation markers, cardiac biomarkers or blood gas analyses were mostly not available and thus were not included here. During the COVID-19 epidemic, occasionally SARS-CoV-2 detection alone was conducted without influenza testing on clinical grounds, however, of the COVID-19 patients included in this study, 21 (75%) were tested for influenza and no co-infections were found. In conclusion, COVID-19 requiring hospitalization had a more severe clinical course than influenza. As SARS-CoV-2 and influenza may continue to circulate simultaneously and influenza already strains health care...

    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.
