They randomized 4116 pts to weight-based Toci vs usual care (UC):
-groups were balanced: mostly male (>65%), older (>60 yo), & w/ comorbidities (>55%)
-most patients (82%) also received dexamethasone
-they received Toci early in hospitalization but were 7-14 days after onset

Notably, only 83% of patients in the Toci group actually received Toci (plus 2.6% randomized to the UC group got Toci); this would decrease the effect size and bias the towards null.
This means their ITT analysis is probably *underestimating* the true effect size somewhat.
