To the Editor: Dr Kumana and colleagues1 explained that "another useful comparative term
is the number (of persons) needed to treat over a given period to prevent
1 person from experiencing an event . . . ." The critical word "additional"
should be added before the word "person," and the phrase "in comparison with
control treatments" should be added at the end of the phrase.
