[PDF] The Cox Proportional Hazards Regression Model
The hazard ratio (HR) between males and females is HR = λmale(t) λfemale(t) = λ0(t) exp(β) λ0(t) = exp(β) = log [λ0(t)] + log [exp(β)] − log [λ0(t)] = β Thus, the proportionality assumption is the same as a constant difference between the log-rates at any time t
