Model specification Variables, coding, and calculation

Cox linear predictor

Calculation: S(t) = S₀(t)^exp(η). The displayed risk score standardizes η to the training cohort; the low/high label uses the frozen training-cohort median. Ordinal MRI descriptors are coded 0–3 from none/minimal to extensive.
