We have carefully reviewed the briefs on appeal and the record in this case. We have had the benefit of oral argument. Our resolution of this case has adhered strictly to the particular arguments asserted on appeal by appellants. We also note that the record in this case is deficient; the primary record evidence relied upon by appellants for crucial elements of its proof is a survey of pharmacists, which was flawed in several respects, including in particular that the survey did not describe actual advertisements at issue or reveal the fact that none of the drugs involved was either approved by FDA or required to be approved. After careful deliberation, and on the basis of the limited record in this case, and addressing only the particular arguments raised by the appellants on appeal, we cannot conclude that the district court committed reversible error. 1

For these limited reasons, the judgment of the district court is

AFFIRMED.
