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. 2020-04-16 · In the example discussed in the "Interpreting the Regression Coefficient" section of that manual, the predictor Age has a coefficient of 0.03. The hazard rate increases by 0.03 (3%) with each unit increase in Age. However, it does not follow that the duration is time is decreasing by the same percentage that the hazard is increasing.
