Multivariate regression analyses predicting GFR.

Variable	β	𝑃 Value
Awake Diastolic BPV (mmHg)	0.553	.003
24-Hr Diastolic BPV (mmHg)	0.595	.001
Awake Rate of DBP Variation (mmHg/min)	0.538	.002
24-Hr Rate of DBP Variation (mmHg/min)	0.621	.001
Awake MAPV (mmHg)	0.284	NS
24-Hr MAPV (mmHg)	0.308	NS

The listed variables were entered separately into a multivariate regression model containing age, BMI, SBP, and DBP. BPV, blood pressure variability; DBP, diastolic blood pressure; GFR, glomerular filtration rate; MAP, mean arterial pressure; MAPV, mean arterial pressure variability.
