All the abstracts at https://academic.oup.com/neuro-oncology/issue/24/Supplement_7 say 'journal article' because, well, those abstracts, dozens and dozens of them, are words written on the journal website... so, 'journal article'. More ammunition for the short sellers... "ahhhh, no journal article ahhwww... crashhh..."
Just click on ANY supplement 7 abstract and you will see the same 'journal article' words. IMHO
