Long-term cognitive outcomes after decompressive hemicraniectomy for right-hemisphere large middle cerebral artery ischemic stroke.

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 purposeDecompressive hemicraniectomy (DH) improves survival and functional outcome in large middle cerebral artery (MCA) infarcts. However, long-term cognitive outcomes after DH remain underexplored. In a cohort of patients with large right-hemisphere MCA infarction undergoing DH, we assessed the rates of long-term cognitive impairment over 3-year follow-up.
methodsWe prospectively evaluated consecutive patients included in the Lille Decompressive Surgery Database (May 2005-April 2022) undergoing DH according to existing guidelines for large hemisphere MCA infarction. We included patients with right-sided stroke and screened with the Mini-Mental State Examination (MMSE) in at least one of the prespecified follow-ups (3-month, 1-year, 3-year). Cognitive impairment was defined as an MMSE score < 24. We included only right-hemisphere strokes to avoid testing biases related to severe aphasia. We compared clinical and neuroimaging data in patients with and without cognitive impairment.
resultsThree hundred four patients underwent DH during the study period. Among 3-month survivors, 95 had a right-hemisphere stroke and underwent at least one cognitive screening (median age = 51 years, 56.8% men). Forty-four patients (46.3%) exhibited cognitive impairment at least once during the 3-year follow-up. Baseline characteristics did not significantly differ between patients with and without cognitive impairment. Regarding long-term temporal trends, cognitive impairment was observed in 23 of 76 (30.3%), 25 of 80 (31.3%), and 19 of 66 (28.8%) patients at 3-month, 1-year, and 3-year follow-up, respectively, and it was associated with higher rates of functional disability (all p < 0.05).
conclusionsThe persistently high rates of cognitive impairment after DH highlight the importance of cognitive monitoring to improve the long-term management of survivors.
