The legends for Figs. 3 and 5 of the article  incorrectly refer to an "all others group". The corrected legends should read: Fig. 3 Exploratory analyses of the impact of sunitinib on overall survival. a OS 2nd line, the "No sunitinib" group may or may not have had sunitinib later. b OS 2nd line, the "Never sunitinib" group excludes patients that had sunitinib at a later time. Fig. 5 OS 3rd line, the "Never regorafenib" group excludes patients that had regorafenib at a later time. Regorafenib improved overall survival by 11.9 months in 3rd line treatment compared to best supportive care with other TKI's and excluding no treatment as best supportive care. Patients that had regorafenib in any treatment line were excluded from the "Never regorafenib" group. A high percentage of patients in "Regorafenib" group were still alive at last follow-up (censored), suggesting an even greater benefit might be possible. Analysis limited to patients reporting progression in 2nd line.
