There was an error in the statistical code used to generate the results presented in this article. The error affected the calculation of the second spline term and the prediction of relative risks in the restricted cubic spline models used for non-linear dose-response analyses in Table 2 and Figure 2 of the manuscript. Corrections have been made to Table 2, Figure 2 and where necessary in the text (page 1931, right column; page 1932, right column) to reflect the correct results. These changes do not affect the conclusions of the manuscript, which remain unchanged.
