Correlation between age-related changes in different organs

Gene set analyzed: non-immune-related genes that showed significant change (P < 0.0077, FDR < 10%, ≥1.5-fold) from 3 to 15 mo in liver (n=531)
Comparison between:			Pearson’s Correlation	Spearman’s Correlation

Liver, 3 to 15 mo	vs	Kidney, 3 to 15 mo	r = 0.28	ρ = 0.28
			P < 0.0001	P < 0.0001
		Lung, 3 to 15 mo	r = 0.17	ρ = 0.14
			P < 0.0001	P = 0.0014

Gene set analyzed: non-immune-related genes that showed significant change (P < 0.0077, FDR < 10%, ≥ 1.5-fold) from 3 to 15 mo in kidney (n=178)
Comparison between:			Pearson’s Correlation	Spearman’s Correlation

Kidney, 3 to 15 mo	vs	Liver, 3 to 15 mo	r = 0.47	ρ = 0.26
			P < 0.0001	P = 0.0004
		Lung, 3 to 15 mo	r = 0.58	ρ = 0.43
			P < 0.0001	P < 0.0001

Gene set analyzed: non-immune-related genes that showed significant change (P < 0.0077, FDR < 10%, ≥1.5-fold) from 3 to 15 mo in lung (n=381)

Lung, 3 to 15 mo	vs	Liver, 3 to 15 mo	r = 0.33	ρ = 0.26
			P < 0.0001	P < 0.0001
		Kidney, 3 to 15 mo	r = 0.50	ρ = 0.39
