Erratum to: Prognostic validation and clinical implications of the EANO ESMO classification of leptomeningeal metastasis from solid tumors

The authors of this article wish to note the following errors or inconsistencies: On page 1108, second full paragraph, the correct p value is 0.0007 (not 0.007). On page 1109, sixth line of text, the correct p value is 0.0003 (not 0.003). There are furthermore two inconsistencies with rounding: In Figure 2H, we provide a p of 0.465 whereas in the text, we state 0.464 (page 1109, line 7). In Table 3, we provide a p value 0.019 whereas in the text, we say 0.018 (page 1109, line 2). The overall conclusions remain unaltered.
