Table 2.

Retrospectively visible interval cancers, i.e. minimal signs or false negative, at different AI risk score thresholds and proportion correctly localised by AI. The thresholds correspond to approx. 10% (score 9.01), 4% (score 9.67) and 1% (score 9.92) recall rates

		Interval cancer classified as minimal signs or false negative
Recall threshold		n, % (95% CI)	Correctly localised, n, % (95% CI)
Total (n = 169)	9.01	96, 56.8 (49.3–64.3)	83, 49.1 (41.7–56.6)
	9.67	56, 33.1 (26.0–40.2)	48, 28.4 (22.1–35.6)
	9.92	20, 11.8 (7.0–16.7)	20, 11.8 (7.0–16.7)
Interval cancer with grave outcome (n = 15)	9.01	9, 60.0 (35.2–84.8)	8, 53.3 (30.1–75.2)
	9.67	5, 33.3 (9.5–57.2)	4, 26.7 (10.9–52.0)
	9.92	3, 20.0 (0.0–40.2)	3, 20.0 (7.0–45.2)
