Question

Which of the following measures of effect are statistically significant? Select all that apply.

A)Odds Ratio = 5.0, p-value = 0.04

B) Incidence Density Ratio = 2.0, 95% CI [0.9 - 3.1]

C) Attributable Risk = 0.5, 95% CI [0.1 - 1.1]

D) Population Attributable Risk = 0.1, 95% CI = [-0.1, 0.2]

E) Cumulative Incidence Ratio = 0.5, 95% CI = [0.1 - 0.9]

F) Odds Ratio = 20, p-value = 0.2

Answer 1

The following measures of effect are statistically significant

A) Odds Ratio = 5.0, p-value = 0.04

Explanation: The p-value of odds ratio is 0.04. This is less than 0.05. Hence this measures of effect are statistically significant.

D) Population Attributable Risk = 0.1, 95% CI = [-0.1, 0.2]

Explanation: The 95 % confidence interval of Population Attributable Risk is [-0.1, 0.2]. This 95% confidence interval does not include 1.0. Hence this measures of effect are statistically significant.

E) Cumulative Incidence Ratio = 0.5, 95% CI = [0.1 - 0.9]

Explanation: The 95 % confidence interval of Cumulative Incidence Ratio is [0.1 - 0.9]. This 95% confidence interval does not include 1.0. Hence this measures of effect are statistically significant.
