Competing Interests

We have read the journal's policy and the authors of this manuscript have NO competing interests. While IG has published a feasibility study of a prognosis tool developed by others, he did not contribute to tool development, and does not own it, or have any financial interest in development of such a tool. This does not alter our adherence to PLOS ONE policies on sharing data and materials. LD, MB, SK and IG have declared that no competing interests exist.
