How about this site? http://www.nntonline.net/ebm/ Click on the "Visual Rx" section--I believe their free software will generate NNT/NNH for you with smiley/frowning faces.
Take care,

Subject: Graphical formats for presenting risk
We are undertaking a randomized study in which we will compare graphical
formats for presenting risk in a scenario for treatment decision making.
For an outcome O we will show risk evidence for treatment A and treatment B
at time T . We are considering comparing pie charts, horizontal bar graphs,
vertical bar graphs, systematic ovals (or faces), random ovals (or faces)
and line graphs.
I'd appreciate input on other graphical preentations that we ought to
consider and of course references to study articles that you might be aware
of would be greatly appreciated.
Sincerely,
Cheryl Carling
