Characterization of Autoantibodies against the E1𝜶 Subunit of Branched-Chain 2-Oxoacid Dehydrogenase in Patients with Primary Biliary Cirrhosis

Table 1

Number of patients with and without anti-BCOADC-E1a and anti-BCOADC-E2 antibodies.

		Anti-BCOADC-E2		Total
		Positive	Negative
Anti-BCOADC-E1a	Positive	16/16 (100.0%)	0/16 (0.0%)	16
	Negative	10/14 (71.4%)	4/14 (28.6%)	14
Total		26/30 (86.7%)	4/30 (13.3%)	30

Note: the incidences of the anti-BCOADC-E1a and anti-BCOADC-E2 antibodies are significantly linked to each other by Fisher's exact test (𝑃=0.037).
