Question

If 50% of women who are diagnosed with venous thrombosis are found to be taking oral contraceptives compared to those without thrombosis, which type of study is this?

• A. Cohort
• B. Case Study
• C. Cross-Sectional
• D. ANOVA

Hint:

Case-control studies are retrospective and useful for studying rare diseases and their risk factors.

Answer 1

The Correct Option is B

A case study (more specifically a case-control study in epidemiology) compares subjects with a particular condition (cases) to those without the condition (controls) to identify factors that may be associated with the condition. - Here, women diagnosed with venous thrombosis (cases) are compared to women without thrombosis (controls) based on oral contraceptive use.
- A cohort study follows a group over time to see who develops the outcome; not applicable here since the data is retrospective.
- Cross-sectional studies measure exposure and outcome simultaneously at a single point in time, not comparing based on disease presence retrospectively.
- ANOVA is a statistical test used to compare means across groups, not a study design.
Therefore, this study is a case study (case-control) design.
