NIH Consensus Statements are prepared by a nonadvocate, non-Federal panel
of experts, based on (1) presentations by investigators working in areas
relevant to the consensus questions during a 2-day public session; (2)
questions and statements from conference attendees during open discussion
periods that are part of the public session; and (3) closed deliberations
by the panel during the remainder of the second day and morning of the
third. This statement is an independent report of the consensus panel and
is not a policy statement of the NIH or the Federal Government.
