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…
Dynamic prediction and analysis based on restricted mean survival time in survival analysis with nonproportional hazards
Zijing Yang, Hongji Wu, Yawen Hou +2
In the process of clinical diagnosis and treatment, the restricted mean survival time (RMST), which reflects the life expectancy of patients up to a specified time, can be used as…
Implementation of an alternative method for assessing competing risks: restricted mean time lost
Hongji Wu, Hao Yuan, Zijing Yang +2
In clinical and epidemiological studies, hazard ratios are often applied to compare treatment effects between two groups for survival data. For competing risks data, the correspond…
Combined tests based on restricted mean time lost for competing risks data
Jingjing Lyu, Yawen Hou, Zheng Chen
Competing risks data are common in medical studies, and the sub-distribution hazard (SDH) ratio is considered an appropriate measure. However, because the limitations of hazard its…
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…
Sample size determination in superiority or non-inferiority clinical trials with time-to-event data under exponential, Weibull and Gompertz distributions
Dong Han, Yawen Hou, Zheng Chen
To examine the effect of exponential, Weibull and Gompertz distributions on sample size determination for superiority trials (STs) or non-inferiority trials (NTs) with time-to-even…
Statistical inference methods for cumulative incidence function curves at a fixed point in time
Jinbao Chen, Yawen Hou, Zheng Chen
Competing risks data arise frequently in clinical trials. When the proportional subdistribution hazard assumption is violated or two cumulative incidence function (CIF) curves cros…
Sample size for a non-inferiority clinical trial with time-to-event data in the presence of competing risks
Dong Han, Zheng Chen, Yawen Hou
The analysis and planning methods for competing risks model have been described in the literatures in recent decades, and non-inferiority clinical trials are helpful in current pha…
