Question

9. A researcher calculated an OR=2.67 to describe the relationship between infectious disease of the pelvis (exposure) and ectopic pregnancy (outcome). She should interpret this to mean that individuals who experienced ectopic pregnancies have 2.67 greater odds of having had an infectious disease of the pelvis than individuals who have not experienced ectopic pregnancies. A. True B. False

Answer 1

Correct Answer :

B. False

EXPLANATION:

Odds Ratio (OR) is a mesure of association between an Exposure and an Outcome.

Here

Exposure : Infectious disease of the pelvis

Outcome: ectopic pregnancy

The OR represents the odds that an Outcome will occur given a particular Exposure, compared to the odds of the Outcome occurring in the absence of that Exposure.

Here, OR = 2.67

The interpretation of OR = 2.67 is as follows:

The odds that ectopic pregnency will occur given infectious disease of the pulvis is 2.67, compared to the odds of the ectopic pregnency in the absence of infectious disease of the pulvis.
