I am doing a Kaplan-Meier analysis utilizing the `sts graph` command.
I want to do a landmark analysis for a specific timepoint.
I would like to analyze it like the following paper.

Ma et al. World Journal of Surgical Oncology (2022) 20:242
https://doi.org/10.1186/s12957-022-02695-y
If anyone knows how to draw a graph like the one above, I would appreciate a response.
Thank you.
