How to read this page
Use relative risk when you want the direct risk multiplier. Use odds ratio when you are comparing with logistic-model outputs, case-control style reporting, or diagnostic odds style interpretation. If you still need absolute intervention impact, continue to ARR / NNT. If you are working from test metrics, diagnostic odds ratio is the closer page.
FAQ
What does this page compare?
It compares two 2x2 groups and reports each group risk, relative risk, odds ratio, and absolute risk difference from event and non-event counts.
Why show both relative risk and odds ratio?
Relative risk is usually easier to interpret as a direct risk ratio. Odds ratio is the scale used in many case-control settings and logistic-model outputs. Seeing both helps you avoid mixing them up.
Does this page calculate confidence intervals?
No. This first release focuses on point estimates only, so you can compare the direction and scale quickly before moving to a fuller analysis.
Does the share URL include my counts?
No. The share URL stores only light settings such as decimal places. The 2x2 table counts stay in your browser.
