Mortality 29% Improvement Relative Risk HRQoL score -28% Paxlovid for COVID-19  Shao et al.  LATE TREATMENT Is late treatment with paxlovid beneficial for COVID-19? Retrospective 1,082 patients in China (December 2022 - February 2023) Lower mortality with paxlovid (not stat. sig., p=0.16) c19early.org Shao et al., medRxiv, May 2023 Favorspaxlovid Favorscontrol 0 0.5 1 1.5 2+
Retrospective 1,082 hospitalized COVID-19 patients in China, showing lower mortality and worse quality of life with paxlovid.
Resistance. Variants may be resistant to paxlovid1-3. Use may promote the emergence of variants that weaken host immunity and potentially contribute to long COVID4.
Confounding by contraindication. Hoertel et al. find that over 50% of patients that died had a contraindication for the use of Paxlovid5. Retrospective studies that do not exclude contraindicated patients may significantly overestimate efficacy.
Black box warning. The FDA notes that "severe, life-threatening, and/or fatal adverse reactions due to drug interactions have been reported in patients treated with paxlovid"6.
AKI. Kamo et al. show significantly increased risk of acute kidney injury.
risk of death, 29.0% lower, HR 0.71, p = 0.16, treatment 280, control 802, day 60.
relative HRQoL score, 28.3% worse, RR 1.28, p < 0.001, treatment mean 0.46 (±0.42) n=237, control mean 0.59 (±0.41) n=456, day 60.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates
