Se Acase-control study was conducted to assess the relationship between alcohol consumption (ALC) and oral cancer (OCA). The table describing the crude data is below Table 1 (n=607). OCA OCA n-74 27 N-533 90 ALC ALC 47 443 1. What is the value of the EOR? а. (27 х 90) (47 х 443) b. (47 х 90У (27 х 443) c. (27 x 443) (47 x 90) 2. What can we conclude about the relationship between the two variables? a. Alcohol consumption is a risk factor for oral cancer. b. Oral cancer is a risk factor for alcohol consumption c. Alcohol consumption is protective against oral cancer. d. There is no relationship between alcohol consumption and oral cancer. 3. If the value of the odds ratio were 5.0, how would it be interpreted? a. The odds of having oral cancer among those who consume alcohol are 5 times the odds of having oral cancer among those who do not consume alcohol. b. The odds of consuming alcohol among those with oral cancer are 5 times the odds of consuming alcohol among those without oral cancer. c. The odds of developing oral cancer are 5 times higher among those who consume alcohol than those who do not consume alcohol.
