Erratum
Unfortunately, the original version of this article [1] contained an error within the results section of the abstract. The sentence beginning with “We found that a one percentage point increase” read “....HR = 1.027, 95 % CI: 1.025–1.027…” but should have read “…HR = 1.027, 95 % CI: 1.025–1.029…” The upper limit of “1.027” was wrong, and was inconsistent with Table 2. This has been corrected in the original article.
