1 · What the graph read from it

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.

2 · The registry

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

purposeLingering inflammation after COVID-19 has been proposed as a contributor to long-term cardiovascular risk, yet the link between pulmonary and vascular inflammation remains insufficiently defined. This study aimed to quantify residual lung and vascular inflammation in individuals recovered from mild-to-moderate COVID-19 using ¹⁸F-FDG PET/CT and assess their association.

methodsFifty-nine participants underwent ¹⁸F-FDG PET/CT imaging at a median of 97 days (IQR: 77-112.5) following clinical recovery from COVID-19. Lung inflammation was assessed using standardised uptake value maximum (SUV

resultsCompared with controls, individuals post-COVID-19 exhibited significantly elevated SUV

conclusionPersistent pulmonary inflammation is evident following mild-to-moderate COVID-19 and is associated with increased vascular inflammation. These findings suggest a mechanistic link between post-infectious lung and vascular inflammation, potentially contributing to elevated cardiovascular risk. ¹⁸F-FDG PET/CT enabled sensitive detection of subclinical inflammation in both compartments, highlighting the value of quantitative PET metrics in elucidating systemic inflammatory response following viral infection.
