I work in a research center affiliated with a University and have free access to most medical journals. I cannot give you the text of the full article without violating copyright, but I did a quick scan for the information. (However, the .PDF of the article is also available for purchase at the Science Direct link in the above post.)
Vitamin C was provided through food sources rather than as a supplement. There are Tables included in the article but you're probably correct that you'll get better information from the principal author. Her email address is
