  1. Number (%) of patients switching/total number of patients by subpopulation: white, 47/212 (22.2%); black, 18/50 (36.0%); employed, 13/69 (18.8%); not employed, 52/193 (26.9%); high school graduate, 46/184 (25.0%); not high school graduate, 15/41 (36.6%); nondiabetic, 27/127 (21.3%); diabetic, 38/135 (28.2%); living at least 30 miles from dialysis clinic 41/155 (26.5%); living less than 30 miles from dialysis clinic 16/61 (26.2%).
