The tissue-specificity of genes identified by different approaches

	LR	QRank	CLS	QRank-LR
No. of identified genes	28066	21726	4788	3631
% of tissue-specific genes	20.7%	43.6%	87.5%	42.0%
RR	Ref	2.111	4.235	2.034
95% CI	Ref	(2.05, 2.17)	(4.13,4.34)	(1.95, 2.13)
P-value	Ref	< 2.2e-16	< 2.2e-16	< 2.2e-16

Note: The relative risk (RR) is calculated as the probability of being tissue-specific genes for genes identified by each approach in comparison with LR.
