What can we infer from the results of the following scenario is for

Question 6 / 7:

The following scenario is for Questions 4?-6:

Consider the table of results displaying odds ratios for the outcome of salmonellosis (yes/no)

and the exposure of beet consumption (yes/no). In the multivariate models, the odds ratios are

adjusted for age, sex, and owning a beet farm.

Odds ratios (and 95% Confidence Intervals)

Variable	Unadjusted	Adjusted
Beet consumption	1.34 (1.19, 1.70)	1.27 (0.98, 1.84)

What can we infer from the results of the adjusted odds ratio?

A Since the confidence interval crosses 1, we cannot infer an association between beet consumption
and salmonellosis.

B We would reject the null hypothesis of no association between beet consumption and salmonellosis.

C The p?-value for the association must be less than 0.05.

D The alpha for this association must be less than 0.05.

E A type I error may have been committed.
