In an (appropriately) private reply, Noah SIlverman told me that "cost effectiveness study" is a well-defined term in epidemiology and that my frustration at his vague description was therefore just a reflection of my ignorance. I accept that and wish to publicly acknowledge my error. My apologies to Noah and the list.
