What likely happens is that the group of patients that end up needing oxygen or more severe than that, they also more likely to have ifn deficiencies as shown before and therefore this particular group is enriched with patients that are more likely to respond. The data points to not much, if at all, virus replication in the lung in icu patients which defies the purpose of giving then, if the mechanism at that stage is anti-viral and not something else. That is perhaps why they want to focus on patients on oxygen, because they are more enriched for patients with ifn deficiencies.
