Placebo-controlled: is it really a MeSH term?

We read this article with great interest. In the methods section
authors mentioned that "Our Medline search used publication type
"randomised controlled trial" and the MeSH term "placebo-controlled" to
identify placebo controlled randomised trials".
Yet an easy MeSH Database search shows that "placebo-controlled" is not a
MeSH term.
