In the dexamethasone group, the incidence of death was lower than that in the usual care group among patients receiving invasive mechanical ventilation (29.3% vs. 41.4%; rate ratio, 0.64; 95% CI, 0.51 to 0.81) and among those receiving oxygen without invasive mechanical ventilation (23.3% vs. 26.2%; rate ratio, 0.82; 95% CI, 0.72 to 0.94) but not among those who were receiving no respiratory support at randomization (17.8% vs. 14.0%; rate ratio, 1.19; 95% CI, 0.92 to 1.55).

With invasive mechanical ventilation death was 41.4%
With oxygen (non invasive) 26.2%

Of course, if there is a mix (as in our trial) the equivalent SOC will be higher than 26.2%. Just name your proportions and calculate the number.

Hint: a split 50%-50% will yield 33.8%

As you can see , depending on how "critical (no pun intended)" the patient is the lower bound for this trial was 26.2%.
