Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

结论:

  • 侧侧额外关节延伸是腿筋自移植ACL重建的有效补充,以减少高风险个体的移植失败.
  • 虽然它没有影响患者报告的整体结果,但该技术的安全性概况与不良事件有关的不良事件值得考虑.
  • 进一步的研究可能会探索优化不良事件的管理,以改善ACL重建后的整体患者满意度.
