The correlation of TIR and parameters of CARTs.

		SBP response to standing (mmHg)	HR variation during lying to standing	HR variation during the Valsalva maneuver	HR variation during deep breathing (bpm)	Total score of CAN
TIR (3.9-10 mmol/L)	R	-0.055	0.167	0.139	0.121	-0.261
	P	0.302	0.002	0.010	0.024	<0.001

TIR: time in range; CARTs: cardiac autonomic reflex tests; SBP: systolic blood pressure; HR: heart rate.
