1. What Is Absolute Risk Calculation?

Absolute risk calculation converts relative risk reduction into actual risk proportion. It helps understand the real-world impact of risk changes by combining baseline risk with relative risk reduction.

2. How Does The Calculator Work?

The calculator uses the absolute risk formula:

Where:

• \( AR \) — Absolute Risk (proportion)
• \( Baseline Risk \) — Original risk proportion (0 to 1)
• \( RRR \) — Relative Risk Reduction (%)

Explanation: This formula calculates the actual risk proportion after applying relative risk reduction to the baseline risk.

3. Importance Of Absolute Risk Calculation

Details: Understanding absolute risk helps in clinical decision-making, treatment evaluation, and risk communication by providing concrete numbers rather than relative percentages.

4. Using The Calculator

Tips: Enter baseline risk as a proportion (0 to 1) and relative risk reduction as a percentage. All values must be valid (baseline between 0-1).

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between absolute and relative risk?
A: Absolute risk shows the actual probability, while relative risk shows the proportional change compared to baseline.

Q2: How do I interpret the absolute risk result?
A: The result represents the proportion of population expected to experience the outcome after risk reduction.

Q3: When should I use this calculation?
A: Useful in medical research, epidemiology, clinical trials, and risk assessment studies.

Q4: What are typical baseline risk values?
A: Baseline risks vary by condition but typically range from 0.01 (1%) to 0.5 (50%) in medical studies.

Q5: Can this be used for risk increases?
A: Yes, use negative RRR values for risk increases (e.g., -20% for 20% increase in risk).
