There are four key components of an AGP:

• Median
• 25th–75th Percentile
• 5th–95th Percentile
• Target Glucose Range

Each of these elements tells a clear story about your patients’ glucose control and variability over a selected time period.

Median (black/blue solid line):

The ‘average’ (middle) point of all glucose levels that shows ‘what usually happens’ during a day.^N Look at whether it is in the target glucose range and how much it swings up and down throughout the day.

25th to 75th Percentile (inner blue-shaded band)

This band indicates where glucose levels are ‘half the time’. Look at width of the band throughout the day. The wider this band is, the more variable the glucose levels are day-to-day.^N

5th to 95th Percentile (outer grey-shaded band)

This band indicates more ‘occasional’ high or low glucose levels. Look at areas where the band is widest, this indicates more day-to-day variation at these times.^N

Target glucose range (two parallel lines at 70-180 mg/dL)

This is the corridor where glucose levels should be as much as possible. According to international consensus, the target glucose range is usually
70-180 mg/dL for adults with type 1 and type 2 diabetes who are not pregnant, not older, or at risk.^B
