Impact of treatment of COVID-19 with sotrovimab on post-acute sequelae of COVID-19 (PASC): an analysis of National COVID Cohort Collaborative (N3C) data.
Article in Infection, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo assess the impact of early sotrovimab treatment versus no treatment on the risk of developing post-acute sequelae of COVID-19 (PASC; long COVID) in patients (age ≥ 12 years) with COVID-19 at high risk for progression to severe disease.
methodsRetrospective cohort study using the US National COVID Cohort Collaborative (N3C) data. Phase 1 identified and assessed multiple definitions of PASC; Phase 2 evaluated the effectiveness of sotrovimab for reducing the risk of PASC, utilizing definitions from Phase 1. Average treatment effect in the treated (ATT)-weighted Cox proportional hazards regression models were used to compare time to event for PASC between high-risk patients who received sotrovimab treatment between May 26, 2021 and April 5, 2022, and high-risk patients with COVID-19 diagnosed between May 26, 2021 and March 26, 2022 who did not receive any treatment for COVID-19 during the acute phase or any pre-exposure prophylaxis against SARS-CoV-2.
resultsA total of 9,504 sotrovimab-treated and 619,668 untreated patients were included in the main analysis. Most baseline characteristics were balanced between the two cohorts after ATT weighting. The doubly robust ATT-weighted hazard ratio (95% confidence interval) was 0.92 (0.89-0.96) (p < 0.001), indicating that sotrovimab use was associated with a significantly lower risk of PASC. Results remained consistent in sensitivity analyses.
conclusionIn patients at high risk for severe COVID-19, the benefits of early sotrovimab treatment may extend beyond the acute phase of COVID-19 and contribute to the prevention of PASC symptoms.
