Time in Range HbA1C diabetes using linear interpolation

[Luanchu]

Hi all,

I am trying to replicate the SAS syntax from this article (https://drc.bmj.com/content/10/4/e002738) to define time-in-range HbA1C but still struggling. Does anyone have experience in defining that before?

Thanks,

James

Provide example data in the form of a working data step pasted into a text box opened on the forum with the </>.

Then provide the code you are attempting and a description of what it does.

Are you interpolating (determining values between recorded values) or attempting to apply the models that generated the graphs. That is very likely to be two different questions.
