Narrative: Side effects
Suppose in a large study investigating side effects of a new drug, it was found that the relative risk of having bad side effects from the new drug (compared to placebo) is 1.3 (with a 95% confidence interval of 1.1 to 1.8).This compares to the relative risk of having bad side effects from the standard drug (compared to placebo), which was found to be 3.4 (with a 95% confidence interval of 1.7 to 7.0), based on large sample results.
-{Side effects narrative} These confidence intervals are not in the usual format of 'sample value plus or minus the margin of error' that we have seen.Explain how we can tell this.
