In the original publication of this article, the end of a sentence in the ‘Cortisol sampling’ section had been mistakenly taken out during production. The sentence should have read:
“Additional saliva samples were provided at 09.00, 12.00, 15.00, 18.00, and 21.00 h.”
This has since been updated in the article, and this erratum published.
The Publisher apologises for this error.
