Odds ratios should be avoided when events are common

Several errors occurred in this letter by Douglas G Altman et al (7 November, p 1318). The last sentence should end “surely it makes sense also to report the relative risk when this differs markedly from the odds ratio” (not “surely it makes no sense …” as printed). Also, the first name of the second author is Jonathan, not Jonathon, and the second author of reference 2 is Bero LA, not Dero LA.
