Web24. Generally speaking, exp ( β ^ 1) is the ratio of the hazards between two individuals whose values of x 1 differ by one unit when all other covariates are held constant. The parallel with other linear models is that in Cox regression the hazard function is modeled as h ( t) = h 0 ( t) exp ( β ′ x), where h 0 ( t) is the baseline hazard.
