Retrospective 3,214 veterans with cirrhosis comparing 1,607 participants taking ursodeoxycholic acid (UDCA) to 1,607 propensity score matched controls not taking UDCA. UDCA use was associated with significantly lower odds of SARS-CoV-2 infection, symptomatic COVID-19, moderate or worse COVID-19, and severe/critical COVID-19.
Standard of Care (SOC): SOC for COVID-19 in the study country, the USA, is very poor with very low average efficacy for approved treatments1. Only expensive, high-profit treatments were approved. Low-cost treatments were excluded, reducing the probability of treatment—especially early—due to access and cost barriers, and eliminating complementary and synergistic benefits seen with many low-cost treatments.
risk of death, 42.0% lower, OR 0.58, p = 0.28, treatment 1,607, control 1,607, adjusted per study, propensity score matching, multivariable, RR approximated with OR.
risk of severe case, 54.0% lower, OR 0.46, p = 0.03, treatment 1,607, control 1,607, adjusted per study, propensity score matching, multivariable, RR approximated with OR.
risk of moderate/severe case, 55.0% lower, OR 0.45, p = 0.002, treatment 1,607, control 1,607, adjusted per study, propensity score matching, multivariable, RR approximated with OR.
risk of symptomatic case, 50.0% lower, OR 0.50, p < 0.001, treatment 1,607, control 1,607, adjusted per study, propensity score matching, multivariable, RR approximated with OR.
risk of case, 48.0% lower, OR 0.52, p < 0.001, treatment 1,607, control 1,607, adjusted per study, propensity score matching, multivariable, RR approximated with OR.

This offers a potential novel target against coronavirus disease 2019 (COVID‐19).
