Diagnostic consistency analysis in papillary thyroid carcinoma with lymph node metastasis of Nrf2 protein expression with HO-1, NQO1,BRAF V600E, CK-19 and Gal-3 protein.

	Intraclass correlation	95% Confidence interval
		Lower bound	Upper bound	p
HO-1	0.836	0.726	0.902	<0.001
NQO1	0.868	0.779	0.921	<0.001
BRAF V600E	0.789	0.546	0.838	<0.001
CK-19	-0.374	-1.300	0.179	0.887
Gal-3	0.510	0.180	0.707	0.003

The intra-group correlation coefficient (ICC) can be used to evaluate the consistency of different measurement methods for the same quantitative measurement. ICC value between 0 and 1, generally considered: ICC 0.75 consistency is good, 0.40~0.75 as a general, <0.40 poor.
