The analyses were performed according to the intention-to-screen principle with the specific aim of comparing intensive (annual) and less intensive (triennial) invitation groups.
Engraved invitations are an acceptable, less labor intensive, substitute.
In 1991, after written invitation, a total of 9,651 participants received intensive health examinations and a detailed health interview.
In 2001, invitations to participate in a two-day intensive workshop in Charlotte, North Carolina or Chicago, Illinois were sent to AHEC directors in six states: North Carolina, Texas, Florida, Oklahoma, Washington, and Utah.
Therefore, the actual screening invitation algorithm was over three times (9.2/2.8) more intensive in the annual invitation group than in the triennial group.
As one of those kids, Tim welcomed an invitation from the Institute for Journalism and Natural Resources to take an intensive tour of this challenging and controversial urban landscape.

If you choose a graphic intensive design, you will use more printer ink and may not save any money by printing the invitations yourself.
