Nirmatrelvir-ritonavir not effective for reducing most post-COVID-19 conditions

A trial emulation study of veterans with COVID-19 found that the use of the antiviral nirmatrelvir–ritonavir was not effective for reducing the risk for many post-COVID-19 conditions, including cardiac, pulmonary, renal, gastrointestinal, neurologic, mental health, musculoskeletal, or endocrine symptoms. Nirmatrelvir–ritonavir was associated only with a reduced risk for combined thromboembolic events. The study is published in Annals of Internal Medicine.
