This seems in line with other studies (like the ones using intravenous immunoglobulin, IVIG) that show moderately immunosuppressive drugs have only a slight benefit but a measurable benefit nonetheless. During early days I was reasonably convinced drugs like IVIG would have a significant positive effect given the ARDS symptoms, but looks like that's not true :( However I'm still fascinated about the possibilities of IVIG therapy - it's essentially a pooled antibody mixture from thousands of donors. IVIG has immunosuppressive effects more than would be expected from its antibodies, and IVIG made this year is bound to have anti covid antibodies as well so it will be interesting to see what effect new ivIG batches would have on patients!
