Autonomic and sensory nerve dysfunction in primary biliary cirrhosis

Table 2 Current perception threshold (CPT) values in PBC patients and controls at median and peroneal nerve testing at three different frequencies

	Patients with PBC (n = 24)	Age-matched controls (n = 20)	P value
CPT (mA)-Median nerve
2000 Hz	2.45 (0.75)	2.94 (0.87)	0.076
250 Hz	0.81 (0.33)	1.10 (0.46)	0.030
5 Hz	0.42 (0.23)	0.50 (0.17)	0.242
CPT (mA)-Peroneal nerve
2000 Hz	2.91 (0.71)	3.61 (0.66)	0.005
250 Hz	1.01 (0.39)	1.40 (0.26)	0.002
5 Hz	0.68 (0.40)	1.06 (0.28)	0.004
