Question
**Study Results and Analysis: Association Between High Blood Pressure and Stroke Risk**

**Study Design:**
This section presents the results of a case-control study aimed at examining the association between high blood pressure (hypertension) and the risk of stroke in adult males. The data is summarized in the following table:

| Status               | Cases of Stroke | Controls |
|----------------------|-----------------|----------|
| High Blood Pressure  | 300             | 200      |
| Normal Blood Pressure| 100             | 200      |

**Analysis Question:**
10. What is the Odds Ratio (OR) estimated from these data?

**Answer Choices:**
- A. OR = 1.00
- B. OR = 0.33
- C. OR = 0.60
- D. OR = 2.00
- E. OR = 3.00

**Explanation:**
The table summarizes the number of cases (individuals who have experienced a stroke) and controls (individuals who have not experienced a stroke) based on their blood pressure status. The Odds Ratio (OR) is a measure used to determine the strength of association between exposure (high blood pressure) and outcome (stroke).
