After publication of this article [1], the authors reported that in the section ‘Sample size and selection process’ in the first sentence, the number ‘1237’ should have read ‘1327’.

Moreover, reference [50] should have been replaced by [53]. References [54–87] were renumbered.

The original article [1] has been corrected.
