Sensor insertion experience
Enrolled patients were asked to complete questionnaires on comfort and ease of use
of G7 insertion. The questionnaires were completed by the subjects or their parents or
guardians.
Ninety-four percent (94%) of subjects responded that the G7 sensor insertion was
painless. A total of 96% subjects found that G7 was easy to use and 98% of subjects
found the IFU easy to understand.
