Comparison of Young's modulus between benign and malignant diseases of prostate gland (${\displaystyle \overline{x}\pm s}$)

Group	No. of patients	PSA (ng/ml)	Young’s modulus(kPa)
			Emax	Emean	Emin
Group of benign	102	14.52 ± 14.03	98.44 ± 43.63	54.47 ± 25.04	20.82 ± 14.71
Group of malignant	113	128.08 ± 108.54	175.82 ± 57.64	95.52 ± 39.65	26.03 ± 21.31
t Value		–11.020	–11.161	–9.165	–2.101
P Value		＜0.001	＜0.001	＜0.001	0.037

Emax, maximum Young’s modulus; Emean, mean Young’s modulus; Emin, minimum Young’s modulus;PSA, prostate specific antigen.
