Erratum

Authors


In the January issue we printed a table that could possibly permit to identify study subjects – an error which to our dismay was not discovered until the issue had been distributed. At each step of the editorial process we inexplicably failed to notice that the table had not been properly anonymised.

The authors have apologised to the study participants; we have protected their data in the electronic version of TMIH; and we have changed procedures in manuscript management. We now apologise to the readers we may have offended with this inexcusable slip.
