Aphasia and Chronic Subdural Hematoma Evacuation: A Retrospective Cohort Study.
Article in Neurosurgery practice, 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
BACKGROUND AND
objectivesThe incidence of subdural hematomas (SDH) is expected to climb precipitously in the coming decades. Aphasia is one of the most common operative neurological symptoms of left-sided SDH. However, the rates of aphasia recovery after SDH evacuation have not been reported as neurological outcomes have been limited to mostly functional assessment scores and mortality. This study represents the first detailed analysis on aphasia and recovery in patients undergoing chronic SDH (cSDH) evacuation.
methodsAdult patients who underwent evacuation of subacute or cSDH at a tertiary academic medical center between November 2013 and December 2021 were retrospectively identified using ICD 9 and 10 billing codes. Patients were categorized by the presence or absence of aphasia at initial presentation. Other clinical and demographic variables were also collected. After surgical evacuation, improvement and resolution of aphasia was recorded at the time of discharge, along with several outcome metrics.
resultsOf the 311 patients requiring cSDH evacuation who met inclusion criteria, 10% presented with aphasia. Risk factors for the development of aphasia were evaluated, including age, sex, hypertension, SDH size, location laterality, and midline shift size. Only left-sided SDH laterality was associated with a significantly greater risk of aphasia compared with right-sided and bilateral SDH (odds ratio 4.89,
conclusionThis study represents one of the first detailed investigations into patients presenting with aphasia in the setting of cSDH. These findings provide unique insights to aid in management and rehabilitation planning of patients with cSDH presenting with aphasia.
