This exchange highlights odds ratios and relative risk effects of therapies in clinical studies, suggesting improved terminology for clinicians.
Our EBM Note denouncing odds ra-tios (ORs) as a means of communication to clinicians of the size of effect of interventions in clinical studies (1) evoked the following strong responses from some notable scholars. In this exchange of letters, OR and RR (relative risk) are 2 ways of describing the effects of therapy; the latter is sometimes subtracted from 1.0 and reported as an RRR (relative risk reduction) (see Glossary).
