Table 4 Multiple linear regression model for predicting carotid-femoral pulse wave velocity (cf-PWV) with age, T1D duration, 24-h-MAP and mean 10-years HbA1c

Model summary

Predictors: Age + T1D duration + 24-h MAP + Mean 10-years HbA1c

Statistics: Adjusted R² = 0.645, F (4,44) = 22.821, p < 0.001***

Regression equation:

Cf-PWV (m/s) = − 10.457 + 0.085 × Age (years) + 0.129 × T1D duration (years) + 0.058 × 24-h-MAP (mmHg) + 0.795 × Mean 10-years HbA1c (%)

Regression coefficients (Standardized Beta) and significance of individual predictors:

Age: β = 0.370, p < 0.001***

T1D duration: β = 0.509, p < 0.001***

24-h MAP: β = 0.206, p = 0.034*

Mean 10-years HbA1c: β = 0.232, p = 0.025*
