Practically everything we know, or think we know, about the medicines used to treat our condition has been gleaned from clinical trials in patients.

Jon, that was a very clear explanation of the terms involved in drug trials. Thank you.

Most reported slight improvement hence the test was deemed a success. They probably were enjoying the experience and attention and that made them feel good.


Yes Jon, a very good and welcome article but I felt I was left hanging off the edge of my seat by the last paragraph - the interface of all these stakeholders... decide collectively ... to build a new gold standard of ...

How do you envisage this interface coming together as an effective force? Shouldn't medical ethicists be included stakeholders?

This could be our finest hour - fighting talk!
