[Feature Request]: landmark endpoints with 95% CI

[zhangq47]

Feature description

Hi, I am in RWDS and appreciate very much using the TEAL4REAL app that Michael Bretscher built for Flatiron RWD analysis. Navi Pal continued on the effort and we are analyzing RWD for early-stage NSCLC (eNSCLC). The eNSCLC patients live relatively longer than late-stage patients, so instead of real-world OS or PFS, the endpoints in eNSCLC are usually landmark endpoints, eg DFS (disease-free survival) and RFS (recurrence-free survival) at 2-, 3-, or 5-year with 95% CI. Can that be added to the TEAL package? Thanks!

Hi @zhangq47

Since OS and PFS are typically controls available in the encoding area of a teal module, I believe you're requesting additional value to the endpoints choices or a new encoding category to control your visualization or output.

Am I correct to assume this?

Hi,

Sorry for the very late reply. I was traveling when I started replying but never got to finish it and send it...

Yes, you are correct. I am asking for 1-yr, 2-yr, 3-yr, 4-yr, 5-yr, etc landmark %survival endpoints. In the example below, Figure panel A, the vertical lines at 12, 24, 36, 48, and 60 months showed Pembro+chemo %survival as 69.8, 45.7, 31.3, 23.6, and 19.4%. Can this be done, and can 95% CI be included as well?

And while we are talking about non-time-to-event endpoints (such as OS, PFS, RFS...), is RR (response rate, also in % format) available or can RR be added?

Thanks! Qing

Hi @shajoezhu @Melkiades,

Can the request be easily fulfilled by passing additional value to one of the module's arguments, or does it require further customization of the related teal module?

I'm going to move this to teal.modules.clinical to get a proper attention.

@zhangq47 could you also provide information which teal module that you're using?
