RLO: Confidence Intervals

 

95% Confidence Intervals

Confidence intervals should be reported in a clinical trial, but see the resources at the end if you want to know how  to calculate them yourself. The actual calculated confidence interval for the relative risk reduction in the trial described above is -4.4% - 70%.

Confidence intervals are created at the 95% level – this means that there is a 5% chance that the true value lies outside this range.
