Which is the best graph to describe a survival analysis with a time-dependent covariate? I am analyzing a randomized trial, and aiming at appraising the impact of a given treatment on a non-fatal outcome, followed occasionally by death. I am thus conducting an event-free survival analysis with a time-dependent covariate (a preceding event). This can be easily modeled with Cox proportional hazard analysis. 
However, I am not sure which is the best graph to describe such time-dependent survival analysis. 
After some research, I have recognized that there are at least three possible alternatives: a landmark survival curve [1], a time-dependent Kaplan-Meier curve [2], and a Simon-Makuch plot [3] (based on the Mantel-Byar testing procedure [4]). 
There is also a related post in CV: Visualize survival analysis with time dependent covariates.
Which is the best graph to depict this scenario? My packages of choice would be R or Stata.

 A: The patients at risk in a survival analysis must start time at risk at entry into the risk set. For a time-dependent covariate, time zero is the time when the at risk unit transfers from the initial to the new status. Thus time at risk in this new state begins at zero and everyone transferring is alive by definition and survival = 1.0 at time zero. The time of transfer in a time-dependent covariate analysis is usually arbitrary. If time at transfer to a new group is fixed, this suggests a possible crossover trial, where crossover time is specified, or some rare biologic condition where timing of group transfer is uniform. Regardless, the best way to graph this new group assignment is to start all units at tome 0 with survival at 1.0.
For example, in the Stanford transplant data, transplant occurs at a random time and it makes most sense to plot two curves beginning at time 0 and survival = 1.0: 1) all patients waiting, 2) those patients transplanted. 

Using the landmark of the transplant time is not possible- the times are non-uniform. Shifting to a shared landmark time is possible, if the time is uniform, but the curve shifted to the right seems to imply implausible survival functions at plausible times at risk following transfer to the new at risk group.
