*, now known with p = 0.000034 from 24 studies, recognized in 3 countries.
Lower risk for mortality, hospitalization, and cases.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Retrospective 19,208 COVID+ hospitalized patients in Spain, 2,071 treated with high dose NAC, showing lower mortality with treatment. In multivariable analysis, authors adjust for corticosteroids, but do not adjust for HCQ use which was also significantly more common in the NAC group. NAC 600mg every 8 hours.
This study is excluded in the after exclusion results of meta analysis: significant unadjusted confounding possible.

Use of N-Acetylcysteine at high doses as an oral treatment for patients hospitalized with COVID-19

Infection by SARS-CoV-2 causing coronavirus disease 2019 (COVID-19) can be associated with serious and life-threatening conditions, including acute respiratory distress syndrome (ARDS). Severity and mortality have been related to a cytokine storm, an imbalance of oxidative stress, and a pro-thrombotic state. We conducted an observational retrospective cohort study from a community-based large population of hospitalized COVID-19 PCR + patients admitted from March 01, 2020, to January 24, 2021, with integrated primary to tertiary care information in Castilla la Mancha, Spain.
