Participants and nonparticipants did not differ significantly on age, race/ethnicity, or staff-rated Karnofsky Index. Although females who were approached at Atlanta area dialysis clinics were less likely than males to actually participate in the study, the percentage of females in the sample (47%) did not differ from the percentage of females starting dialysis 1995-97 in the U.S.
More recent studies have used the Karnofsky index to predict outcomes.
