Q-Score Complements the Time in Range in the Evaluation of Short-Term Glycemic Control
Authors' conclusion
The Q-Score is a tool for assessing short-term glycemic control. The Q-Score can be translated into clinician opinion using the GRI.
Study context
- Population
- People with DM treated with intermittent continuous glucose monitoring (CGM) for ≥14 days1,562 three-day-sensor profiles for target range (TAR) adjustment
- Participants
- 302 people
- Outcome
- Q-Score refinement for short-term glycemic control
Methodological detailsnoninterventional
- Noninterventional
Main finding
As reported in the abstract
- Correlation between Q-Scores with TAR 8.9 and 10 mmol/L (Q-ScoreTAR10 = −0.03 + 1.00 Q-ScoreTAR8.9)
- r = .997, p < .001
- Time to stability of Q-Score
- 10 days
- Time to stability of time in range (TIR)
- 12 days
- Correlation of Q-Score with fructosamine
- r = .698
- Correlation of Q-Score with glucose management indicator (GMI)
- .887
- Correlation of Q-Score with TIR
- −.874
- Correlation of Q-Score with glycemic risk index (GRI)
- .941
- Q-Score components above target, CGM profiles with TIR 70%–80%
- two (1.7 ± 0.9)
- Q-Score components above target, majority of CGM profiles with TIR <50%
- four (3.9 ± 0.5)
Observational data: associations, not effects.
