affects their lifestyle. More and more research is showing, however, that much longer and much more frequent dialysis are what make the biggest difference in extending life.
Their is a city in France where the last option listed (8 hours x 6 days) is the norm, and their clinical outcomes are off the charts (relatively speaking). Their patients are on almost no medications like you'd normally see in kidney failure patients.
6-8 treatments are much more common in Europe and Japan, and yet they're pretty rare in the US. It's almost entirely a matter of how it affects the patient's lifestyle.
So, really the question is how much time you'd be willing to invest in treatments if it meant living longer. Also, keep in mind that the average patient is around 60-65 years old, but there are a significant number of patients in their 30s and 40s.
