This calculator computes the relative risk for a 2x2 crosstabulation, which measures the ratio of the risk of developing a condition (or disease) for those exposed to a risk factor, versus the the risk of exhibiting the condition for those that are not exposed to the risk factor. Total better a+b= a = b = total no better c+d :

Relative risk calculator helps you find the comparitive risk occurence of a significant event for two groups. Confidence interval tells the likely probability of the risk ratio, in such a manner, let’s say a 90 percent confidence interval for a risk ratio 1.40 will have less accuracy than a confidence interval of 99 percent with a risk ratio of 1.30.
