Association of PFR with parameters of TCNS, VPT and NCV.

	PFR
	rs	P-value
TCNS	−0.183	< 0.001
VPT	−0.245	< 0.001
MMN-NCV	0.239	< 0.001
PMN-NCV	0.313	< 0.001
MSN-NCV	0.274	< 0.001
PSN-NCV	0.291	< 0.001

The Spearman correlation analysis was used to evaluate the association of PFR with parameters of TCNS, VPT and NCV. Bold indicates statistical significance (P < 0.05).

MMN, median motor nerve; MSN, median sensory nerve; NCV, nerve conduction velocity; PFR, prealbumin to fibrinogen ratio; PMN, peroneal motor nerve; PSN, peroneal sensory nerve; TCNS, Toronto clinical neuropathy score; VPT, vibration perception threshold.
