1.069 and a 95% CI = (1.037, 1.102), over the study period. This is similar to the previous model, but not exactly the same. However, it is also now significant. Age as metameter Adv: Don’t need to specify how hazard changes with age, so less likely to misspecify it. Disadv: Cannot obtain a valid parameter estimate for age. Controlling for age in model Adv: Can model how age is associated with outcome (if model misspecifications are correct). Disadv: Must specify how hazard changes with age, and can bias estimate if you misspecify. 8)List one advantage and one disadvantage of using the Cox model for survival analysis versus using Poisson regression. 9
