In the author list, J. Infante should have been affiliated with institutions 3 and 9, rather than just 9, as appears correctly in the author list of this erratum.

There were a number of errors in Table 2, involving the names of institutions listed in column 1. Minor errors were present in institutions 25 (Hospital da Costa, Burela), and 39 (Centro Neurológico OMS 42) within the table. In addition, the ‘Complementary studies’ column of institution 38 (Hospital Josep Trueta and Parc Martí i Juliá) should have read ‘15/10’. As a result, the row of totals found at the bottom of Table 2 was incorrect for this column, and should have read ‘315/110’.

Table 2 appears correctly in this erratum.

Finally, there were errors in the COPPADIS Study group (collaborators) section. The sentence “Finally, this author will not participate in the study” was mistakenly included between the names of Ferriol MM and Leiva C. In addition, the collaborator Clemente J should have appeared as ‘Segundo JC’.

Within the affiliations of this section, the city names of institutions 19 (Hospital Clínico San Carlos, Madrid) and 20 (Hospital da Costa, Burela, Lugo) appear incorrectly.
