Content of review 1, reviewed on April 22, 2025

  1. The small sample size, with a total sample of only 166 cases, may affect the statistical power, especially in subgroup analyses.
  2. PCU relies on patients' recollections and medical records, and there is a memory bias (especially for patients in the advanced stage who may have blurred memories).
  3. Confounding factors were not adequately adjusted: Factors that might affect the PCU, such as comorbidities and family nutritional support, were not included in the analysis.
  4. The research period coincided with the peak of the COVID-19 epidemic, and its potential interference with the results was not analyzed.
  5. Lack of multi-center validation.
  6. The lack of in-depth discussion on the interpretation of the results.
