摘要

Shin 等人的文章就胃黏膜相关胃微生物组（MAM）与远期复发之间的相关性提供了有价值的见解。然而，他们在分析中使用的 Cox 比例危险模型存在一些局限性。该研究可能会导致混合普查结果，而且随着时间推移危险比恒定的假设可能不成立。考虑到这些局限性，未来的研究应采用其他方法，如加速衰竭时间（AFT）模型，以更全面地了解胃癌 MAM 与远期复发之间的关系。

Limitations of the cox proportional hazards model and alternative approaches in metachronous recurrence research

The article by Shin et al. provides valuable insights into the correlation between the gastric mucosa-associated gastric microbiome (MAM) and metachronous recurrence. However, the use of the Cox proportional hazards model in their analysis presents several limitations. The study may result in mixed censoring outcomes, and the assumption of constant hazard ratios over time may not hold. Considering these limitations, future research should adopt alternative approaches, such as the accelerated failure time (AFT) model, to provide a more comprehensive understanding of the relationship between gastric MAM and metachronous recurrence.
