Brett...Please be sure to post the source of the data, where it was published etc. if you wish for it to stay on the board. Also remember that data which is four years old, may be still accurate or may not reflect the most current thinking in all things. This is a field where discoveries and trial results appear on a daily basis. What we knew four years ago may have been now superceded by something different. Posting references allows all to judge for themselves, and reading the original study in it's complete form, to determine if the information is still of value, appropriate for them, something to bring up to their docs etc.
