From: Important prognostic factors for survival in patients with malignant pleural effusion
Kaplan-Meier curves showing the relationship between ECOG performance status (PS) and survival in patients with MPEs. A significant difference was observed in survival for patients with an ECOG grade of 1 to 4 (Chi-square = 242.15, p < 0.0001). ECOG scores of 1 (HR: 1.67, 95% CI: 0.93-3.01, p > .05), 2 (HR: 2.13, 95% CI: 1.24-3.67, p < .05), 3 (HR: 3.72, 95% CI: 2.26-6.11, p < .05) and 4 (HR: 10.50, 95% CI: 5.96-18.50, p < .05) are shown.
