Recurrence-free survival and overall survival curves in patients within the Milan criteria (solid lines), beyond the Milan criteria but within the Warsaw expansion (short-dashed lines), beyond the Milan criteria and Warsaw expansion but within either the UCSF or the up-to-7 criteria (dotted lines), and beyond both the UCSF and the up-to-7 criteria (long-dashed lines) (a, b) and in patients within (solid lines) and beyond (dashed lines) the Warsaw criteria (c, d). Numbers of patients at risk are presented below the particular graphs
