What about the 8 patients who increased narcostic use?
The data I quoted was from B57. In it there were 2 patients that increased narcotic use NOT 8.
I also compared the 6 who dropped narcotic use with the total in the study (51) when the comparison may be more proper to the evaluable n of 23.
I chose the data to meet your concern for objective data.
Given that 2 had increased narcotic use, and 9 decreased including 6 who dropped it entirely, the question remains whether you consider the data sufficiently objective.
It is astonishing what foolish things one can temporarily believe if one thinks too long alone ... where it is often impossible to bring one's ideas to a conclusive test either formal or experimental. J.M. Keynes
