Dear all,
Several weeks ago I asked you to respond to the survey regarding
grading "All or None evidence" (shown below).
Unfortunately, I had only 10 people responding to this survey (out
of ???? how many on the list-does anybody know?). However, results of this
small sample show a tremendous disagreement (with almost equal distribution
over all possible choices) that it would be quite interesting to learn what
other folks think about this issue. Consequently, if you are interested I
would be happy to continue receiving your responses regarding this issue (or
issue about current ranking of evidence in general). To avoid annoying
others with individual answers, please send your response directly to me. I
would be happy to summarize results for the group again. Thanks.

Survey
Using Oxford grading of medical evidence (see:
http://cebm.jr2.ox.ac.uk/docs/levels.html) ranking of "ALL or NONE" findings
is:
a) appropriately placed
b) appropriately placed only if n of "ALL or NONE" series =>
6, 8, 10, 12, 14, 16, 18, 20
(choose 1)
c) should be ranked as 1a, 2b, 1c, 2a, 2b, 2c, 3a, 3b,
4, 5 level of evidence
(choose 1)
d) ranking cannot be determined outside applicability of
this evidence within a given clinical context and prior knowledge (about
this therapy)
