Plotinus, thanks for this snippet from the journal article.
Mild translation attempt for a lay person: "8 of the 10 were on pressor agents".
Eight were sick enough (septic, sepsis?) (cytokine storm?) that their bodies needed medicines ("agents"
to maintain their blood pressure. Yes, that is critically or severely ill.
Crazy---yes---infuriating---yes, even more than 3 years out.
