Single arm remdesivir trial with 145 hospitalized patients showing no statistically significant difference between "early" and "late" administration, however the treatment delays may be better described as late and very late. The text of the paper defines early and late as less than or more than 7 days from symptom onset, however the CONSORT diagram says during or after 7 days post admission.
