Comparison of mean capsule thickness between small (n=10) and large (n=10) prostates

Two-sample t-test
Group	Sample size	Mean	SD	Variance	P-value
Small prostates (<30 g)	30 microfields	0.883	0.439	0.192	P<0.001 (99.9% CI)
Large prostates (≥80 g)	30 microfields	1.467	0.547	0.299

Note: Statistically significant P-value shown in bold.
