The number of patients with T1D included in the study.
Fig 2.
Observed mean and standard error of the mean of change from baseline HbA1c for T1D-CGM vs T1D-NOCGM.
The statistically significant asterisk notation is from a multiple linear regression model with change from baseline HbA1c as the dependent variable, time as the independent variable and HbA1c at baseline as the reference, i.e. the statistical significant notation refers to baseline within the group. Available HbA1c values in the quarter before each time point contributed to the means.
Fig 3.
Mean and standard error of the mean of change from baseline HbA1c for subgroups in the T1D-CGM group.
The upper left graph (Fig 3A) shows patients with HbA1c ≤ 86 mmol/mol at baseline versus patients with HbA1c > 86 mmol/mol at baseline. The upper right graph (Fig 3B) shows patients aged ≤ 68 years versus patients aged > 68 years. The bottom left graph (Fig 3C) is females versus males. The bottom right graph (Fig 3D) shows patients with a diabetes duration ≤ 21 years versus patients with a diabetes duration > 21 years. The estimates were derived from general linear models with change from baseline in HbA1c as the dependent variable, time as the independent variable and HbA1c at baseline as the reference. Available HbA1c values in the quarter before each time point contributed to the estimates. Statistically significant changes are marked with an asterisk and refers to baseline within the group.

Table 2.
Mean, 95% confidence interval (95% CI) and p values for change from baseline HbA1c and for number of hospital visits per year for T1D-CGM and T1D-NOCGM.
Estimates were derived from t tests. p value for hospital visits is for test of difference between groups, whereas p values for change from baseline HbA1c is difference before and after baseline within each group.
Table 3.
Adjusted differences in change from baseline HbA1c (mmol/mol) between T1D-CGM and T1D-NOCGM and within the T1D-CGM subgroups of age, sex, HbA1c at baseline and diabetes duration.
Estimates and p values are from multiple linear regression models adjusted for age, sex, diabetes duration and use of CSII (Y/N).
