The objective of a study is to determine the surgery mortality rate. It was well speculated that age is a confounder. Thus, the investigator would like to estimate the death rate by controlling for age effect. Explain which methods, age-adjusted rates or Poisson regression with age adjustment, would you use? Explain and justify your choice.
