AGP for clinical trials:

Currently the IDC uses our CaptūrAGP® system as well as a SAS® program for producing research AGPs. The research AGP includes a second row of statistics: Glucose Variability, Exposure and Episodes close ups.

Our systems are able to produce SMBG, CGM and Insulin Pump + CGM reports. We can produce batched reports for different time periods, demographic sub populations and intervention arms. IDC provides AGP interpretation as well as research analytic reporting. If you want us to produce AGPs for your next research trial; we would be glad to help.

Research CGM AGP Report (Continuous Glucose Monitor)

Extended Statistics - Normally used in research, several of these will be blank if the data is from SMBG

Episodes close up: Episodes start when readings are within one of these ranges for at least 15 minutes; episodes end when there is a reading that is in target (70 -180). Fewer episodes are best for all these measures.
Avg. Min. per Day: How long in minutes the episodes of hypo- or hyperglycemia are per day on average
Mean Episodes/Day: How many episodes occur per day on average
Mean Duration (Min.): How long the episodes last on average

AUC Hourly: Measure of the space/ “area” beneath the median orange line; lower is better. Glucose exposures by period
Wake: between 6am and midnight Sleep: between midnight and 6am 24 Hours: from midnight to midnight

IQR (interquartile range): The range between the 75% and the 25% blue lines. The blue shaded area on the profile graph represents 50% of all the glucose measures. Ideally this shaded area is narrow, which shows less variation.
MAGE (Mean Amplitude of Glycemic Excursion): Measures the distance from a glucose high point to the low point or vice versa. This is the average of all excursions including the MAGE+ (going from low to high) and the MAGE– (going high to low); normally several per day. Lower is better.
MODD (Mean of Daily Differences): Compares the glucose level between two different days to help you understand the glucose patterns day to day. A patient with a higher MODD, has glucose patterns that fluctuate more widely. Lower is better.
LGBI (Low Blood Glucose Index): Index (0 – 100) of how many and how low glucose readings were in the measurement period. A high score means that there might be lots of mild low readings or a few very low readings or some of both. A low index is best.
HBGI (High Blood Glucose Index): Index (0 – 100) of how many and how high glucose readings were in the measurement period. A high score means that there might be lots of mild high readings or a few very highs or some of both. A low index is best.

Ongoing scientific trials:

  • A pilot project with Glooko to examine patient interpretation of the AGP CGM + Pump report.
  • NIH funded pilot study using Glooko AGP Report investigating patient barriers to diabetes management. (PI - Rich Bergenstal, MD)
  • Partnership study with Barbara Davis Center for Diabetes and IDC - using the AGP Report for patient downloads at home. (PI - Todd Alonso, MD)
