ESCAPE (metastatic renal cell carcinoma): reconstructed Kaplan–Meier curves
Efficacy and Safety of First-Line Cytokines versus Sunitinib and Second-Line Axitinib for Patients with Metastatic Renal Cell Carcinoma (ESCAPE Study): A Phase III, Randomized, Sequential Open-Label Study. Curves rebuilt as patient-level data (Guyot 2012) and checked against the statistics printed on the figure.

2nd-line progression-free survival
From figure panel B · validated against the values printed on the figure · curve source: vision model
Reconstructed from the published curve. Median: Sunitinib 3.8 months; IL-2+IFNα 15.3 months. Survival at 12 months: Sunitinib 40%; IL-2+IFNα 61%. Hazard ratio IL-2+IFNα vs Sunitinib 0.58 (95% CI 0.19–1.76).
