Correction to: Nature Communications https://doi.org/10.1038/s41467-018-03819-3, published online 16 April 2018.

The original version of this Article contained an error in the ‘Methods’ subsection entitled ‘Broad depression phenotype’, which incorrectly read ‘“Have you ever seen a psychiatrist for nerves, anxiety, tension or depression”? (UK Biobank field 2010)’. The same error was made three times in the subsections ‘Probable MDD phenotype’ and ‘ICD-coded MDD phenotype’, which read ‘(UK Biobank fields: 2090 and 2010)’. The correct version states ‘2100’ in place of ‘2010’ in each case. This has been corrected in both the PDF and HTML versions of the Article.
