The following table comes from a case-control study that examined the relationship between alcohol consumption and pancreatic cancer.

Table 2. Age-adjusted odds ratio (AOR) estimates for total alcohol consumption and alcohol type.

Use the numbers in the table to calculate the unadjusted (not age-adjusted) odds ratio comparing the odds of being a case in the >=21 drinks/week group to the odds of being a case in the
