^*Patient enrollment in CHOICE occurred over a nearly 3-year period, from October 1995 to June 1998; our cross-sectional facility survey was distributed in October 1998. Thus, the numbers of patients being treated with PD in the clinic may have differed between time of patient enrollment and the facility survey, from which we obtained PD clinic size. Additionally, although clinics reported PD clinic size as the total number of PD patients treated at their clinic, not all treated patients were enrolled in the CHOICE study.
