Reference coding was used for each variable. The reference group for each variable was labeled with ref.
Region is defined as follows: East includes Connecticut, Atlanta (Metropolitan), and Rural Georgia; Northern Plains includes Detroit (Metropolitan) and Iowa; Pacific Coast includes San Francisco-Oakland, Hawaii, Seattle (Puget Sound), San Jose-Monterey, and Los Angeles; and Southwest includes New Mexico and Utah. Because no patients with APL were reported from Alaska during 1992-2007, the region of Alaska is not listed.
