Table 3.

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;
