Retrospective 600 PCR+ outpatients in Australia treated with ivermectin, zinc, and doxycycline, showing significantly lower mortality and hospitalization with treatment. This trial uses a synthetic control group, and the preliminary report provides minimal details.
For discussion of the use of a synthetic control group, see1. Notably, advantages include less-biased recruitment (patients do not opt-out if they feel they need treatment and don't want to risk placebo), trials are cheaper, there is less delay in treatment, and trials can be run where it is not ethical to give patients placebo.
This study is excluded in the after exclusion results of meta-analysis:
combined treatments may contribute more to the effect seen.
Study covers ivermectin and zinc.

risk of death, 92.3% lower, RR 0.08, p = 0.03, treatment 0 of 600 (0.0%), control 6 of 600 (1.0%), NNT 100, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm).

risk of hospitalization, 92.9% lower, RR 0.07, p < 0.001, treatment 5 of 600 (0.8%), control 70 of 600 (11.7%), NNT 9.2, primary outcome.
