However, this usage is potentially ambiguous since the Cox proportional hazards model can itself be described as a regression model. Cox’s regression which is the proportional hazards assumption that the hazard ratio between two groups remains constant over time.

I use SPSS for statistical analysis of a study. The study look into how a blood test predicts mortality with patients followup of 1 year. Patients were divided into quartiles, and using the first quartile as a reference group I used Cox regression to determine the unadjusted Hazard ratios (HR) and the adjusted HR for quartile 2-4.
