Real-World Glycemic and Person-Reported Outcomes After Tandem Control-IQ Initiation in Children With Type 1 Diabetes
Authors' conclusion
One-year use of Control-IQ was associated with improved glycemic management, more diabetes-related quality of life and fewer school/work absences.

- Participants
- 114 children
- Exposure
- 12 months after Control-IQ initiation vs start of Control-IQ
- Outcome

Main finding
As reported in the abstract
TIR (3.9-10.0 mmol/L) · 12 months
P < 0.001
Observational data: associations, not effects.
Further findings
HbA1c · 12 months · decreased
P < 0.001
HbA1c % 12 months 7.1% [6.9-7.3] · Start 7.8% [7.6-8.1]
| Outcome | 12 months | Start | P value |
|---|---|---|---|
| Time <3.9 mmol/L · 12 monthsDecreased | 2.7% (95% CI 1.9–3.5) | 3.9% (95% CI 3.1–4.8) | P < 0.001 |
Person-reported outcomes (DQOLY satisfaction and impact, HAPPI-D, HFS worry)
- Children scored better on DQOLY satisfaction and DQOLY impact; parents on HAPPI-D and HFS worry (all P < 0.001)
School and work absences
- Children missed fewer days of school (P < 0.001)
- Parents missed fewer days of work (P < 0.001)
