The effect of YM value in distinguishing the CKD

R-C YM value	Cut off (kPa)	Sensitivity	Specificity	AUC (95% CI)	P
Control group vs CKD group	4.05	0.931	0.971	0.964 (0.922-1.000)	< 0.001
Mild vs Moderate	5.75	1.000	0.400	0.709 (0.566-0.852)	0.025
Moderate vs Severe	7.50	1.000	0.769	0.862 (0.685-1.000)	0.021
Mild vs Severe	7.60	1.000	0.900	0.963 (0.909-1.000)	0.001
R-M YM value	Cut off (kPa)	Sensitivity	Specificity	AUC (95% CI)	P
Control group vs CKD group	2.95	0.828	0.986	0.915 (0.857-0.973)	< 0.001
Mild vs Moderate	3.95	0.923	0.525	0.761 (0.615-0.906)	0.005
Moderate vs Severe	5.25	0.800	0.923	0.877 (0.674-1.000)	0.016
Mild vs Severe	5.42	1.000	0.850	0.963 (0.900-1.000)	0.001

R-C: renal cortex; R-M: renal medulla; IF: interstitial fibrosis; CKD: chronic kidney disease; AUC: under the curve; YM: Young’s modulus.
