Breast stiffness in patients with 1 surgerized breast and 1 unaffected breast

Patient group	N	Breast stiffness mean (SD)		p-value^a
		Unaffected breast	Surgerized breast

Average risk	7	1.07 (0.12)	1.07 (0.15)	–
High risk	33	2.33 (1.23)	2.22 (1.17)	–
Total	40	2.11 (1.21)	2.02 (1.15)	0.14

The p-value was based on a paired t-test comparing breast stiffness in the unaffected versus surgerized breast. The sample was limited to patients who underwent biopsy or surgery on one breast but not the other
