    Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:
    Limitations: Our findings should be interpreted in light of certain caveats, most of which relate to the characteristics of the included studies. First, most studies were conducted in the US and Canada and relied on CMS data, which means that (1) the results primarily relate to North America, and (2) there may be overlap in the analysed data across certain studies. Second, the body of included research was too heterogenous to be meaningfully meta-analysed and this version of the review thus represents a critical appraisal and narrative synthesis conducted in line with best practice standards 20,57. Last, throughout our risk of bias assessments, we assumed that the reporting of COVID-19 outcomes was not systematically related to ownership. However, there is some suggestive evidence of a longer turnaround period for resident test results among for-profit providers 58, which if generally true, may bias the effect of FP status towards the null due to underreporting. Conclusion and future research: This review constitutes the first version of a living appraisal and synthesis of evidence on ownership variation across COVID-19 outcomes. It will be updated as new research becomes available, which may change the conclusion of our synthesis. Based on our synthesis of the available research, we find FP status to be a consistent and credible risk factor of higher cumulative COVID-19 infections and deaths. Therefore, ownership among care home providers may be a key regulatable factor that...

    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.
