Are pooled results possible for the m/m and s/c trials? Both trials collect the "7-category ordinal scale" (1=death,7=out of hospital, no restrictions) at the 14 day mark.

Either just pool the patients, or more precisely, use an ANOVA or its non-parametric cousin. It would likely be treated as a "post-hoc secondary endpoint."

I took the risk of wasting NP's time by sending him the briefest message on the subject.
