The Oxford site is malfunctioning today, so here is the one abstract of
the study that is not coming up:

http://www.ncbi.nlm.nih.gov/pubmed/11865409

and when it works once again you can click on the journal icon on your
upper right of that page to get to the free article. (You can also use
that icon trick at PubMed to at times get to journal articles for
purchase.)
