Ethics not detected. Sex as a biological variable Ethics statement and COVID-19 hamster models: Experiments including female and male hamsters (Mesocricetus auratus; breed RjHan:AURA, JanvierLabs, France) and Roborovski hamster (Phodopus roborovskii, via German pet trade) were approved and executed in compliance with all applicable regulations (permit number 0086/20). Randomization not detected. Blinding Histopathology and in situ-hybridization of SARS-CoV-2 RNA: For histopathology and in situ-hybridization (ISH), lungs were processed, and tissues evaluated by board-certified veterinary pathologists in a blinded fashion following standardized recommendations, including pneumonia-specific scoring … SciScore for 10.1101/2021.12.17.473180: (What is this?)

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:That notwithstanding, future studies should ideally compare patient data to the findings reported here with the obvious constraint of limitations in the availability of corresponding human biomaterial. In summary, we found that broadly active anti-inflammatory and immunosuppressive agents such as dexamethasone may have a strong benefit in SARS-CoV-2 infection at high risk for severe disease when applied before the onset of severe illness, particularly when combined with an anti-viral agent. A recent analysis showed that COVID-19-related ARDS patients can be classified into hypo- and hyperinflammatory types, with corticosteroid treatment being beneficial only for the latter (51). Animal models as the ones described here can help to better dissect causes and types of COVID-19 lung pathologies, and thus help to improve therapeutic strategies.
