Change in HbA1c at 3 months
Arm | Mean difference (95% CI) | P value | ||
CGM (n=28) Mean (SD) |
UC (n=11) Mean (SD) |
|||
HbA1c at follow-up | 7.4 (1.9) | 7.9 (2.0) | ||
Crude change from baseline | −1.2 (1.9) | 0.2 (2.7) | −1.38 (−2.92 to 0.17) | 0.08 |
Model 1 | −0.88 (−2.15 to 0.40) | 0.17 | ||
Model 2 | −1.07 (−2.39 to 0.26) | 0.11 |
Model 1 adjusted for baseline HbA1c only; Model 2 adjusted for baseline HbA1c, facility site, age, sex, diagnosis year and BMI. Note: 28 of the original 29 were included from the CGM arm because 1 person did not have a follow-up HbA1c measurement, and 11 of 13 were included in the UC arm because of missing follow-up measures.
CGM, continuous glucose monitoring; HbA1c, haemoglobin A1c; UC, usual care;
