Question

Match List I with List II:

List I (Study design)	List II (Analytical outcome)
A. Case-control study	III. Odds ratio
B. Cohort study	I. Relative risk
C. Cross-sectional study	IV. Prevalence
D. Descriptive study	II. Time, place, and person distribution

Choose the correct answer from the options given below:

• (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
• (A) - (II), (B) - (IV), (C) - (I), (D) - (III)
• (A) - (IV), (B) - (III), (C) - (II), (D) - (I)
• (A) - (I), (B) - (III), (C) - (IV), (D) - (II)

Hint:

Matching study designs with their analytical outcomes is essential for understanding how each design evaluates specific epidemiological measures.

Answer 1

The Correct Option is A

The correct matches are:

• A. Case-control study: The outcome is Time, place, and person distribution, focusing on identifying associations in specific settings.
• B. Cohort study: The outcome is Prevalence, assessing the frequency of a condition over a given time.
• C. Cross-sectional study: The outcome is Relative risk, estimating the likelihood of disease presence in relation to exposure.
• D. Descriptive study: The outcome is Odds ratio, measuring associations between risk factors and outcomes descriptively.

Thus, the correct sequence is: (A) - (II), (B) - (IV), (C) - (I), (D) - (III).
