Dexamethasone had the best survival rate in that population at the time we were enrolling. That's why the 25% mortality is the worst case for study results. But about 50% of the patients in the SOC/placebo arm were actually on placebo before we accepted SOC. Of the rest I would think not many were on corticosteroids and most of the rest were on drugs that did little to nothing. So that should be quite a bit higher than 25%.
