Recurrence-free survival outcomes for breast cancer patients by DeepGrade risk-group obtained on the biopsy specimen. A. Kaplan-Meier curves for patients stratified by biopsy DeepGrade-low and -high risk groups. The high-risk group had the worst prognosis. B. Forest plot from multivariable Cox proportional hazard regression including the biopsy DeepGrade risk groups and age at diagnosis. Three patients had missing data for age. C. Kaplan-Meier curves for ER-positive/HER2-negative patients stratified by biopsy DeepGrade-low and -high risk groups. D. Forest plot from multivariable Cox proportional hazard regression for ER-positive/HER2-negative patients including the biopsy DeepGrade risk groups and age at diagnosis
