Time In Range (TIR)

What do you have your TIR set at for CGM data? Mine is set from 3.9-7.9, but it was previously preset to 10 (which I don’t feel is “in range”). I really think TIR should be 4-7, but I think I’d feel discouraged if I saw my graphs within that range.

I used to use 70-150 (3.9-8.3) for TIR, but changed back to the “industry standard” of 70-180 (3.9-10) because its what my Endo and PCP use, but they endorse tighter range control if it’s doable for the person. The Trio dev’s added 70-140 (3.9-7.8) for TITR (Time in Tight Range) to the stats page of their app. I believe TITR was first addressed at the 2019 ATTD conference and several articles over the past year advocate it as a goal.

My personal goal is 90+% TIR and 65+% TITR. I make the first goal a lot of the time when I’m home and can maintain a normal diet, I fall far short when traveling. I fall short of the TITR goal most of the time. Below is a pic of the Trio stats page, I think it’s very similar to an AGP page. While the graphs are good, I think the important line is at the bottom, including GMI, SD, and CV (discussed elsewhere here on FUD). They have their problems, but it’s hard to hide poor BG control with all three. For anyone not familiar with them, a good article on SD and CV is: https://diatribe.org/diabetes-management/understanding-average-glucose-standard-deviation-cv-and-blood-sugar-variability

Keep in mind everyone’s results will vary based on activities, treatments, and life in general. Goals should be hard to achieve, but not impossible, and shouldn’t get in the way of living (I should talk! My wife says I’m a bit “obsessive”!).

I think 70-140 is reasonable. Because realistically, 70-140 on the Dexcom is probably closer to 50-180 for actual BG.

I use 70-160, figuring 160 is halfway between 140 and 180 and I usually notice and attempt to correct a rising high BG after it passes 140 but before it rises past 180. Seemed to make sense as a personal benchmark.
