After publication of the original article [1], the authors noticed that there were errors in the caption of Fig. 3, and the y-axis of Fig. 6 itself. The following statement should not have been included in the caption of Fig. 3: "CNS-LS scores were not normalized." The CNS-LS is a rank-order scale, and is not normalized. This statement was included erroneously and the authors intended on removing it prior to resubmission, but this was unfortunately overlooked. Similarly, the y-axis within Fig. 6 was mislabelled. The CNS-LS scale ranges from 7 to 35, so the y-axis for Fig. 6 should start at a base score of 7 and not zero. The correct and updated version of Fig. 6, in which the data presented remain accurate and are unchanged, is published in this erratum.
