    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:
    Our study has several limitations. First our study was performed at one health network with a relatively small number of patients potentially limiting generalizability. However, the associations between ambulatory hypoxia and worsening oxygenation were statistically very strong. Second, we excluded patients who did not have ambulatory oximetry measurements. Ambulatory oxygen measurement is part of the admission order protocols in our health system, so patients without measurements likely represented a sicker cohort unable to ambulate or those discharged quickly. Patients without measurement may also have been cared for by clinicians who did not order ambulatory oximetry, given lacking evidence. Third, we did not directly measure the presence of resting hypoxia because it was often not documented in the medical record before the use of oxygen therapy. The use of oxygen therapy was used as a surrogate for resting hypoxia. Finally, we excluded all patients who used oxygen therapy before ambulatory oximetry measures. These patients likely underwent ambulatory oximetry to determine discharge readiness. Alternatively, there may have been a small number of these patients who were given NC treatment for subjective comfort without resting hypoxia, who then developed ambulatory hypoxia. Future randomized studies should be performed to evaluate earlier interventions in patients with COVID-19 and ambulatory hypoxia without resting hypoxia. An important extension of our findings could be ...

    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.
