Colwiz is unable to find a paper on the sidebar. I then went to the browser and got the cchrome extension. I clicked add to colwiz. It says it is added. I go back my library and it still is not there.
I need this paper cited:Lenchik, L., & Boutin, R. D. (2018, July). Sarcopenia: Beyond Muscle Atrophy and into the New Frontiers of Opportunistic Imaging, Precision Medicine, and Machine Learning. In Seminars in musculoskeletal radiology (Vol. 22, No. 03, pp. 307-322). Thieme Medical Publishers.
