Design outcomes

Primary

MeasureTime frame
Time in Range (TIR) during exercise in comparison of EASD/ISPAD paper- and app-based group vs. standard of care (superiority; efficacy outcome) Time below range 1 (TBR1; <70 mg/dL) during exercise in comparison of EASD/ISPAD paper- and app-based group vs. standard of care (superiority; safety outcome)

Secondary

MeasureTime frame
TIR during exercise in comparison of EASD/ISPAD app-based group vs. paper-based group (non-inferiority) TBR 1 during exercise in comparison of EASD/ISPAD app-based group vs. paper-based group (non-inferiority) Time above range 2 (TAR; >250 mg/dL), TAR 1 (181-250 mg/dL); TIR, TBR 1 and TBR 2 (<54 mg/dL) in comparison of the three groups for the pre-, during and post-exercise condition Glycaemic variability (%CV and SD) in comparison of the three groups for the pre-, during and post-exercise condition Numbers of events per person of TBR 1 and TBR 2 in comparison of the three groups for the pre-, during and post-exercise condition
