Mean Difference in Systolic Blood Pressure
Zeitfenster: Baseline and 3 months

Mean difference between 3 months and baseline systolic blood pressures (in mmHg) by group.

Change in Endothelial Dysfunction as Assessed by the Reactive Hyperemic Index
Zeitfenster: Baseline and 3 months
|
Endothelial function was measured by the EndoPAT device - difference at 3 months - baseline, by group.
The outcome reported is the Reactive Hyperemic Index (RHI).
The RHI is a measure of endothelial vasodilator function.
The RHI is the post-to-pre occlusion peripheral arterial tone signal ratio in the occluded arm relative to the other arm, which is not occluded.
Persons with worse endothelial function have a lower RHI score.
Consequently, a low RHI indicates more endothelial dysfunction.
A value of 1.67 or less is considered abnormal vascular tone.
The reported lower and upper limits in adults with type 2 diabetes is 1.1 - 4.9.

Change in the Epworth Sleepiness Scale
Zeitfenster: Baseline and 3 months
|
The Epworth Sleepiness Scale measures self-reported sleep propensity or daytime sleepiness.
The range of the scale is 0 to 24 (integers only), with increasing values corresponding to increasing sleepiness.
A cut-point of ≥ 11 is also sometimes used to differentiate those with pathological sleepiness (≥ 11) versus those without < 11.
The difference between the three month final visit - the baseline visit score is reported by group

Change in Post-Pre Meal Blood Glucose Levels
Zeitfenster: Baseline and 3 months
|
The difference from baseline to three months in self-reported in blood glucose levels before and after meals (mg/dL) (post-meal - pre-meal).
Data is presented for breakfast, lunch, and dinner.
