AI Pathology Test Achieves C-Index of 0.71 Across 5 Independent Cohorts and 3,502 Patients
kjgeras · x · 2026-07-06
The AI pathology model predicted disease-free survival across 5 independent validation cohorts (totaling 3,502 patients) that were never used in training. It achieved a C-index of 0.71 and a hazard ratio of 3.63 (per 0.2-point increment), demonstrating robust cross-cohort generalization capabilities.
