To the editor: We recently discovered that the unbound bilirubin values shown in figure 1 of our paper entitled ‘Influence of clinical status on the association between plasma total and unbound bilirubin and death or adverse neurodevelopmental outcomes in extremely low birth weight infants’, Acta Paediatrica, 2010 99: 673–678 may be confusing to the readers [1]. In the process of performing the logistic regression probability plots to correlate the unbound bilirubin with various outcome variables, we have standardized the unbound bilirubin by dividing the actual values by the standard deviations which is 0.3. The standardized values (in units) were used in the presentation of data in this figures which appear to be 0–3.0 units. The actual unbound bilirubin values are 0–0.9 mcg/dL A footnote should have been appended. We apologize for this omission.
