Geographic differences in trial characteristics, the poor alignment between trial numbers and COVID-19 disease burden, and lack of international collaborations suggest that better integration of clinical research efforts is warranted to combat a global public health crisis. PubMed entries associated with the indicated intervention are shown, including publications describing experiments that directly assessed In vitro or in vivo anti-viral activity ./cache/cord-299882-ee5wathm.txt ./txt/cord-299882-ee5wathm.txt
