A number of minor errors and omissions occurred in the above mentioned article [Reference Charlson, Baxter, Dua, Degenhardt, Whiteford and Vos1], which are given below.

The following text ought to have appeared in the results section of the abstract:

The 13 million excess deaths reported should be treated with caution as the sum of excess deaths of individual disorders are not additive or control for comorbidity between mental and substance use disorders.

Page 127, line 14, where it reads “There were no deaths causally attributed to intellectual disability; however, excess deaths in people with idiopathic intellectual disability were estimated to be substantial at over 900 000 deaths globally in 2010.” the author wishes to add the following comment:

This estimate of excess deaths relates to ALL underlying causes of intellectual disability, not just those from idiopathic origin.

Page 127, line 5 of the Substance use disorders section, ‘5 million’ should be revised to ‘1.95 million’.

Page 127, fig. 4, the top left graph should be as is displayed in the re-numbered fig. 4.a below:

Page 127, the captions for fig. 4 should read as follows:
