Extended Data Table 6 Performance breakdown

From: International evaluation of an AI system for breast cancer screening

  1. The analysis excludes technical recalls and US cases for which BI-RADS scores were unavailable. a, Sensitivity across cancer subtypes in the UK data. We used the first reader operating point (i) shown in Fig. 2a. Also shown is the performance of the first reader on the same subset. b, Sensitivity across cancer subtypes in the US data. We used the operating point shown in Fig. 2b. Reader performance was derived from the clinical BI-RADS scores on the same subset. ILC, invasive lobular carcinoma; IDC, invasive ductal carcinoma; DCIS, ductal carcinoma in situ. c, Performance across breast density categories. BI-RADS breast density was extracted from the radiology report rendered at the time of screening, which was only available in the US dataset. We used the operating point shown in Fig. 2b. Adjusted specificities were computed using inverse probability weighting (Methods).
