This randomised trial in Pediatric Diabetes looked at whether sending blood glucose levels over the internet to carers resulted in better glycemic control among adolescents with type 1 diabetes.
However, the trial only had 70 participants, and around one third did not comply with the intervention, rendering the results almost meaningless. Although the authors carried out a sub-group analysis on those that complied, the observed improvement in HbAc1 was not statistically significant.
Readers of this paper should consider:
- The small sample size
- The lack of compliance
- The mechanism by which the intervention might improve glycemic control.
