Other	Number of Participants With Karnofsky Performance Status (KPS) Less Than 80 Percent (%)	KPS: used for rating participant activities of daily living on scale from 0-100, higher score = participant is better able to carry out daily activities. Score range: 100 = normal no complaints; no disease evidence, 90 = able to carry normal activity; minor signs/symptoms of disease, 80 = normal activity with effort; some signs/symptoms, 70 = cares for self; unable to carry on normal activity, 60 = requires occasional assistance, but able to care for most personal needs, 50 = requires considerable assistance and frequent medical care, 40 = disabled; requires special care, assistance, 30 = severely disabled; hospital admission is indicated although death not imminent, 20 = very sick; hospital admission necessary, 10 = moribund; fatal processes progressing rapidly and 0 = dead. The lower the score the worse is survival for most serious illnesses. Here, number of participants with KPS <80% were reported.
