    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 had several limitations. First, we compared data obtained from two surveys with different methodologies: data of Omicron group from telephone interviews, and those of control group from a self-reported questionnaire-based online/paper-based survey, which may have influenced the results. Second, those with more severe symptoms might less likely to respond to telephone calls if they were subsequently hospitalized, making data on the critically ill more likely to be scarce. Third, the self-reported questionnaire-based online/paper-based survey was subject to various biases, such as selection, volunteer, and recall biases. In particular, the survey was limited to COVID-19 convalescent plasmapheresis patients who underwent the pre-donation screening test. It is unclear whether the results of this survey can be applied to all patients recovering from COVID-19. Forth, this was a single-center study with a small sample size. Fifth, the definition of post COVID-19 condition in this study was similar to a previous study [3]. However, whether the symptoms could be explained by an alternative diagnosis remains unclear in our study. Therefore, our findings may have overestimated the prevalence of post COVID-19 condition. Sixth, some patients had persistent symptoms at the time of the survey. In these cases, the actual duration of the symptoms was unclear. Long-term observation is needed to better understand the duration of post-COVID conditions of Omicron. Seventh, it was imposs...

    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.
