Lies, Damn Lies and Statistics

Every procedure has its table of statistics. It always shows you how their process is superior to others. It's like trying to buy a mattress. No two stores sell the same mattress. It's some industry rule or something (really). You can try to copy down specifics about each as you go from store to store, but ultimately you realize that process is hopeless and buy the one that "feels" best.

One common problem I'm seeing with everyone's data is that it groups all men with prostate cancer into one bucket. For example, the da Vinci process states that 86% of patients have sexual function at 12 months. OK, I have two questions about that. One, exactly what is their definition of "sexual function"? Second, what is the success rate for men under 50 who have this procedure? It seems logical to me that the success rate of such a procedure can largely be dependent on the age of the patient. Eh?
