Sample size calculation based on the difference in restricted mean time lost for clinical trials with competing risks
Xiang Geng, Zhaojin Li, Chengfeng Zhang +5
Computation of sample size is important when designing clinical trials. The presence of competing risks makes the design of clinical trials with time-to-event endpoints cumbersome.…
Time-varying effect in the competing risks based on restricted mean time lost
Zhiyin Yu, Zhaojin Li, Chengfeng Zhang +3
Patients with breast cancer tend to die from other diseases, so for studies that focus on breast cancer, a competing risks model is more appropriate. Considering subdistribution ha…
Analysis of dynamic restricted mean survival time based on pseudo-observations
Zijing Yang, Chengfeng Zhang, Yawen Hou +1
In clinical follow-up studies with a time-to-event end point, the difference in the restricted mean survival time (RMST) is a suitable substitute for the hazard ratio (HR). However…
Restricted mean survival time regression model with time-dependent covariates
Chengfeng Zhang, Hongji Wu, Baoyi Huang +3
In clinical or epidemiological follow-up studies, methods based on time scale indicators such as the restricted mean survival time (RMST) have been developed to some extent. Compar…
A Nonparametric Statistical Method for Two Crossing Survival Curves
Xinghui Huang, Jingjing Lyu, Yawen Hou +1
In comparative research on time-to-event data for two groups, when two survival curves cross each other, it may be difficult to use the log-rank test and hazard ratio (HR) to prope…
The use of restricted mean time lost under competing risks data
Jingjing Lyu, Yawen Hou, Zheng Chen
Background: Under competing risks, the commonly used sub-distribution hazard ratio (SHR) is not easy to interpret clinically and is valid only under the proportional sub-distributi…
