Discriminatory performance after adjustment for age of the image-based risk model and the Tyrer-Cuzick v8 risk model throughout the first years after study entry. The image-based risk model included 8,604 women in the subcohort and 2,208 breast cancers. Tyrer-Cuzick included 8,483 women in the subcohort and 1,904 breast cancers. The horizontal line denotes the aAUC point estimate (0.65) of the image-based risk model for 10-year of follow-up in the study sample. The corresponding aAUC for Tyrer-Cuzick was 0.60. The aAUC point estimate differences between the image-based risk model and Tyrer-Cuzick ranged from 0.12 (1-year follow-up, P < .01) to 0.05 (10-year follow-up, P < .01). aAUC, AUC after adjustment for age; AI, artificial intelligence.
