a
Data represent number of patients and corresponding row percentages (%) except for treatment characteristics in which column percentages are shown.
b
Median household income for patient’s area of residence.
c
Data estimated by population of patient’s county using data from 2013 published by United States Department of Agriculture Economic Research Service. Metropolitan represents counties in metropolitan areas with a population range of fewer than 250 000 to greater than 1 million; urban represents populations of 2500 to greater than 20 000, either adjacent or not adjacent to a metropolitan area; rural represents completely rural populations or areas with less than 2500 residents.
