Structural Brain Abnormalities and Neuropsychiatric Symptoms in Post-COVID Condition.
Article in NeuroImmune pharmacology and therapeutics, 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
Objectives: We aimed to cross-sectionally and longitudinally compare brain morphometry and neuropsychiatric symptoms, and evaluate their relationship, in participants with Post-Coronavirus Disease Condition (PCC) and healthy Controls. Methods: At Baseline, 29 PCC (19 female; average age=42.4±12.2 years; 242±156 days since infection) and 25 Controls (14 female; 44.1±12.3 years) completed the NIH Toolbox Emotion, Motor and Cognition Batteries; Patient Reported Outcomes Measurement Information System (PROMIS); and structural brain MRI (thickness, areas, volumes). We compared neurobehavioral performance on the NIH Toolbox and PROMIS and structural brain morphometry for 34 cortical regions and 8 subcortical volumes, between PCC and matched Controls at Baseline (~8 months post-infection) and 11 PCC and 7 Controls at a Follow-Up Visit (~3 years post-infection). Results: At Baseline, PCC had significantly larger putamen and amygdala (FDR-corrected Conclusions: Structural abnormalities in PCC suggest compensatory processes such as enhanced myelination or neurogenesis, rather than neuroinflammation, which in turn may contribute to persistent neurobehavioral symptoms. However, these alterations and symptoms may improve three years after infection.
