I agree, @Lorraine. It took me awhile to read this style of report but I now look for the following items to see if my control over the days, in this case 7, has been poor, fair, good, better, or best. You likely have the same sensibilities but I wanted to help readers understand better what they’re looking at.
- Is the average (red diamond) within the target range? If yes, good. If no, not so good and a good time slot to target effort.
- Are any of the bottom edges of the blue rectangles, the 25th percentile, piercing the lower target threshold? If no, good. If yes, not so good and and a good time slot to target effort. It’s best to shoot for the 10th percentile to be within the green stripe.
- Are the top edges of the blue rectangles exceeding the top target threshold? If no, good. If yes, an indication to target effort.
In other words, the best possible performance (and not realistically likely) would be a straight line with the averages somewhere around 85 mg/dl, very small rectangles, and short candlesticks above and below but everything contained within the green stripe. Ideal, but not real world. It helps to understand the image, however.
I never took statistics in school but I’ve learned a lot from diabetes.
