FAQ
What does this page calculate?
It calculates each group risk, the risk ratio, and the absolute risk difference from one 2x2 table of event and non-event counts.
How is this different from the relative risk and odds ratio page?
This page stays focused on the risk ratio and the absolute risk gap for a quick 2x2 read. The relative risk and odds ratio page adds odds ratio when you need both scales side by side.
Does this page calculate confidence intervals?
No. This first release is for quick point estimates only, so you can confirm the direction and scale 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. Your 2x2 counts stay in your browser.
