Testicular SWE values and CV in two probes and four ROI sizes

ROI (mm)	SWE (Kpa)		P value	CV (%)
	SL10–2	SL15–4		SL10–2	SL15–4
4	2.15 ± 0.103	2.00 ± 0.090	< 0.001	4.7	4.5
6	2.20 ± 0.120	2.04 ± 0.095	< 0.001	5.4	4.6
8	2.27 ± 0.127	2.15 ± 0.100	< 0.001	5.5	4.6
10	2.43 ± 0.140	2.23 ± 0.110	< 0.001	5.8	4.9
P value	< 0.001	< 0.001

The data are expressed as mean ± standard deviation. Analysis of variance (ANOVA) demonstrated statistically differences in the testicular SWE values obtained by using different ROI sizes. The t–test revealed statistically differences in testicular SWE values between the SL10–2 and SL15–4 probes within the same ROI size.
