PSM retrospective 6,218 hospitalized COVID-19 patients in China showing lower 28-day all-cause mortality with azvudine treatment compared to controls (HR 0.63, 95% CI 0.40-1.00). Subgroup analysis found significantly faster clinical improvement when azvudine was initiated within 5 days of symptom onset compared to controls.
Although the 37% lower mortality is not statistically significant, it is consistent with the significant 34% lower mortality [20‑46%] from meta analysis of the 13 mortality results to date.
risk of death, 37.0% lower, HR 0.63, p = 0.048, treatment 428, control 428, propensity score matching.
risk of no improvement, 2.9% lower, HR 0.97, p = 0.73, treatment 428, control 428, inverted to make HR<1 favor treatment, propensity score matching.

Background: Clinical effectiveness of Azvudine against coronavirus infection and optimal time for initiation of Azvudine treatment to hospitalized COVID-19 patients are not fully understood. Methods: This is a multi-center retrospective cohort study, and ve clinical centers of the Chinese People's Liberation Army General Hospital participated. From omicron pandemics, 6218 hospitalized patients con rmed with COVID-19 from December 10, 2022, to February 20, 2023, were retrieved for this study. After exclusions and propensity score matching , 428 Azvudine recipients and 428 controls were included with a follow-up of 28 days. The primary outcome was all-cause mortality during 28 days of hospitalization, and the secondary outcome was the proportion of patients with clinical improvement up to day 28. Results: The Azvudine group had a lower crude all-cause death rate when compared to the control group (2.82 per 1000 person-days vs. 4.52 per 1000 person-days; HR: 0.63, 95%CI: 0.40-1.00; P=0.038). Notably, the incidence rate of clinical improvement outcome was signi cantly higher in patients who received Azvudine within 5 days from the onset of symptoms, compared to the control group (Median days: 9 vs. 10; P=0.007). Subgroup analyses showed that chronic lung disease and corticosteroid treatment acted as protective factors (P=0.010; P=0.050). Conclusions: Clinical effectiveness of Azvudine in improving all-cause mortality in COVID-19 patients was seen, and initiation of Azvudine treatment within 5 days of the onset of symptoms was found to be signi cant. Additionally, the ndings revealed the protective effect of Azvudine in COVID-19 patients with chronic lung disease.
