Table 1. Baseline demographical and clinical characteristics of participants (n = 223).

^aPerformance status, as defined by the Eastern Cooperative Oncology Group criteria, is an objective index of a patient's physical functioning, ranging from 0 (no symptoms) to 4 (bedridden).

^bPalliative Prognostic Index was defined by Palliative Performance Status, oral intake, edema, dyspnea at rest, and delirium. For patients who had a score ≥6.5, 3 weeks' survival was predicted with a sensitivity of 80% and a specificity of 85%. For those who had a score of 3.6–6.4, 6 weeks' survival was predicted with a sensitivity of 80% and a specificity of 77%.

^cSome patients had multiple etiologies of delirium.
