Brain Structural Abnormalities in Patients with Post-COVID-19 Headache.
Article in Neurology international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06825741 (Brain Structural Abnormalities in Patients with Post-COVID-19 Headache), which is not on this 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.

Abstract
BACKGROUND/
objectivesHeadache is one of the most common neurological symptoms associated with COVID-19, affecting approximately 25% of patients. While most headaches resolve within weeks, some persist for months, suggesting underlying structural brain changes. This study aimed to identify brain MRI abnormalities associated with chronic headaches in patients with a history of COVID-19 infection.
methodsThis retrospective study included 30 patients with post-COVID-19 headaches and 30 control patients with no history of COVID-19. Demographic characteristics were analyzed using
resultsWhite matter lesions were significantly more frequent in the post-COVID-19 group (50%) compared to controls (20%) (
conclusionsPersistent post-COVID-19 headaches may be linked to structural white matter changes observed in MRI. Further research, ideally including pre-infection imaging data, is needed to determine the causal relationship between these lesions and chronic headache symptoms.
trial registrationThis study was registered in ClinicalTrials with the trial registration number NCT06825741 on 13 February 2025.
