A researcher wishes to test whether an antecedent factor is associated with a certain type of respiratory infection. Using an appropriately articulated case-control study she observes the OR (95% CI) to be 1.10 (0.78, 1.22). The observed OR suggests that the antecedent factor is associated with Question 10 options: Statistically significant risk at the 5% significance level Possible or weak risk that is probably not statistically significant at the 5% significance level Statistically significant protection at the 5% significance level Possible or weak protection that is probably not statistically significant at the 5% significance level
