Obenchain RL. Issues and algorithms in cost-effectiveness inference. Biopharmaceutical Reports 1997; 5: 1-7. [NOTE: My first ICE paper is now mostly out-of-date in the sense I have since changed key terminology. Still, it clearly shows that some of my basic ICE concepts that remained unpublished (in a refereed journal) until 2008 are actually much older.] View/Download.
