Case -2% Improvement Relative Risk Case (b) -4% UDCA for COVID-19  Liu et al.  Prophylaxis Does ursodeoxycholic acid reduce COVID-19 infections? Retrospective 226 patients in China No significant difference in cases c19early.org Liu et al., Liver Int., June 2023 FavorsUDCA Favorscontrol 0 0.5 1 1.5 2+
Retrospective 280 Chinese families with children previously seen in a liver clinic assessing whether ursodeoxycholic acid (UDCA) reduced SARS-CoV-2 infection risk. Among infected families, the study found no significant difference in confirmed or suspected SARS-CoV-2 infections between children taking UDCA (80.9%) and those not taking it (77.6%) (p=0.843).
Standard of Care (SOC): SOC for COVID-19 in the study country, China, is average with moderate average efficacy for approved treatments1.
risk of case, 2.1% higher, RR 1.02, p = 0.88, treatment 95 of 146 (65.1%), control 51 of 80 (63.7%), confirmed.
risk of case, 4.3% higher, RR 1.04, p = 0.61, treatment 118 of 146 (80.8%), control 62 of 80 (77.5%), confirmed + suspected.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

SARS‐CoV‐2 infection was confirmed in 226 families (80.7%): 146 children were taking UDCA (10‐20 mg/kg/day) and 80 children were not taking UDCA.
