Table 1. Basic statistics and PCC values for four cases shown in Fig 1.

The correlation values for AD-related genes were relatively larger than those for AD-unrelated genes. However, the correlation values for AD-related genes were not sufficient to accurately determine correlations in AD.

AD-unrelated genes	Case (see Fig 1)	Class label	Gene	Mean of expression values	Standard deviation of expression values	PCC of two expression lists
	(A)	Normal	ACTR1B	0.099	0.284	0.021
			TMEM45B	-0.882	1.207
	(B)	AD	ACTR1B	-0.070	0.304	-0.080
			TMEM45B	-0.832	1.094
AD-related genes	(C)	Normal	APOE	0.359	1.475	-0.590
			APP	-0.135	0.952
	(D)	AD	APOE	0.997	1.369	-0.280
			APP	-0.817	0.906
