Hanes, John C.
American Journal of Evaluation, v23 n2 p165-82 Spr 2002
Describes the number needed to treat (NNT) as an indicator of a program's efficacy. L'Abbe plots compare several programs in terms of the event rates that constitute the NNTs. Explains how an evaluator may extend the NNT concept by calculating and plotting event rates on a continuous ordinal basis. (SLD)
