a) Median survival for patients in the good (score, zero to two), intermittent (score, 2.5 to four), and poor (score, more than four) prognostic groups according to the initial PPI categories (red: good prognostic group; yellow: intermittent group; and green: poor prognostic group). b) Subgroup survival analysis of patients with score changes (Δscore) in different prognostic groups according to the initial PPI categories (red: good prognostic group; yellow: intermittent group; green: poor prognostic group; solid line: Δscore = 0; fine dashed line: Δscore > 0; and coarse dashed line: Δscore < 0). HR = hazard ratio.

The c-statistic at the best cutoff point among the initial PPI, Week 1, score change (Δscore), and combined initial PPI and Δscore for predictions of life expectancy <30 days (upper and lower ends of the columns represent the 95% CIs for each c-statistic). ∗A significant difference in the c-statistic compared with the combined initial PPI and Δscore; P <  PPI = Palliative Prognostic Index.
