Examining neuroimaging biomarkers, plasma biomarkers and cognitive functions in patients with recovered COVID-19 infection: a multicentre study using 7T MRI.

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
We examined the impact of COVID-19 hospitalization on neuroimaging biomarkers and the association of these neuroimaging biomarkers with cognitive measures and plasma biomarkers. A total of 179 dementia-free people, including 52 hospitalized COVID-19 patients, across four medical centres in the USA and UK underwent 7T brain MRI scans, cognitive tests and blood collection. We found that hospitalized patients exhibited a comparable white matter hyperintensity burden, lower total hippocampal volume and lower plasma glial fibrillary acidic protein concentration, along with poorer memory performance, compared to age-matched non-hospitalized participants. Higher white matter hyperintensity burden was associated with older age, worse cognitive scores and higher plasma biomarker levels; higher total hippocampal volume was associated with younger age, better cognitive scores and lower plasma phosphorylated tau levels. However, these correlation coefficients did not differ between the hospitalized and non-hospitalized groups. Longitudinal studies are needed to clarify the long-term impact of COVID-19-related hospitalization.
