Paxlovid shows organ-specific and age-specific impacts on risk of developing post-acute sequelae of COVID-19.
Article in Communications medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe impact of antiviral therapies, including Paxlovid, on post-acute sequelae of COVID-19 (PASC) remains inconclusive.
methodsWe analyzed data from 19,413 patients (age > 18) from a validated PASC research cohort in New England who experienced at least one COVID-19 infection episode between January 1, 2022, and June 7, 2022, totaling 22,094 episodes. Multivariable logistic regression with inverse probability weights was used to infer the causal effects of Paxlovid treatment during acute infection and the risk of PASC overall (primary outcome), stratified by age group and organ system.
resultsAcross all age groups, Paxlovid shows no statistically significant effect in lowering overall PASC risk. Stratification by organ system reveals a 37% reduction in gastrointestinal PASC (OR: 0.63; 95% CI: [0.468, 0.850]; p < 0.05) but a 97.4% increase in the risk of eye and ear-related PASC (OR: 1.974; 95% CI: [1.048, 3.718]; p < 0.05). Among patients aged 65 to 75 years who were not hospitalized, Paxlovid is associated with a 16.8% reduction in PASC risk (OR: 0.832; 95% CI: [0.7, 0.989]; p < 0.05). No statistically significant effects is observed for other organ-specific outcomes.
conclusionsPaxlovid demonstrates organ-specific effects on the risk of PASC, with a reduction in gastrointestinal symptoms and an increased risk of eye and ear-related symptoms. In older, non-hospitalized patients, Paxlovid modestly reduces overall PASC risk. These findings highlight the complexity of antiviral therapy's long-term impact and underscore the need for further research to clarify the mechanisms underlying these outcomes.
