COVID-19 Disease as an Acute Angiotensin 1-7 Deficiency: A Preliminary Phase 2 Study with Angiotensin 1-7 in Association with Melatonin and Cannabidiol in Symptomatic COVID19 -Infected Subjects
et al., Journal of Infectiology,
Small study with 30 patients treated with melatonin, cannabidiol, and for 14 patients angiotensin 1-7, compared with an age/sex matched control group during the same period, showing lower hospitalization with treatment.
risk of hospitalization, 90.9% lower, RR 0.09, p = 0.05, treatment 0 of 30 (0.0%), control 5 of 30 (16.7%), NNT 6.0, relative risk is not 0 because of continuity correction due to zero events (with reciprocal of the contrasting arm). With the observed event rates, ~4 more patients per arm would result in statistical significance.
Effect extraction follows pre-specified rules prioritizing more serious outcomes.
Lissoni et al., 12/30/2020, prospective, Italy, Europe, peer-reviewed, 14 authors, this trial uses multiple treatments in the treatment arm (combined with cannabidiol and angiotensin 1-7) - results of individual treatments may vary.
