Following publication of the original article [1], the authors flagged an error in Addition file 6.

The error is in the coefficient estimates presented in Column 2 of the table; exponentiated values are presented instead of standard OLS coefficients.

Please therefore now be referred to the corrected version of Additional file 6 contained in this article.

The results and analysis of the article are not affected by this error.

The authors apologize for any inconvenience caused.
