Mastectomy type	Positive test result (n = 235)	No positive test result (n = 108)	P value^b
Radical	40 (17.0) [12.2-21.9]	15 (13.9) [7.3-20.4]	.76
Simple	43 (18.3) [13.3-23.3]	21 (19.4) [11.9-26.9]
Partial	152 (64.7) [58.5-70.8]	72 (66.7) [57.7-75.6]

^{^a}

We included a total of 343 patients with breast cancer with BRCA test results who had medical claims within 12 months before or after documented BRCA test results in this analysis (after removing 3368 patients without breast cancer and 1822 patients without medical claims within 12 months before or after documented BRCA test results).
