Pooled Kaplan–Meier curves showing survival probabilities for patients (n = 680) from three high-quality RCTs (Bakitas et al., 2009, 2015; Temel et al., 2010) who were randomized to outpatient specialty palliative care versus control. Median survival was 4.56 months greater (χ2 = 9.04; df = 1; p = .0026) for patients randomized to outpatient specialty palliative care (median survival = 14.55 months; 95% CI, 12.50 to 19.20 months) than for patients in the control condition (median survival = 9.99 months; 95% CI, 8.59 to 11.40 months). Individual-patient data were reconstructed from published Kaplan–Meier curves to yield pooled curves [42].
