Awake Craniotomy in Patients With Language Deficits: A Retrospective Cohort Study in 48 Patients.
Article in Operative neurosurgery (Hagerstown, Md.), 2026. 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
objectivesThis retrospective cohort study reviewed the feasibility and applicability of awake surgery for glioma in patients with clinically relevant preoperative language deficits, specifically focusing on intraoperative language monitoring and its impact on postoperative language outcomes.
methodsGroup and individual analyses were conducted to compare preoperative and postoperative language deficits. In addition, an overview of intraoperative tests was provided, and an evaluation of the monitoring process was performed.
resultsIn 100% of patients with significant (z score ≤ -1 SD) preoperative language deficits (N = 48), language tasks could be performed during awake surgery. In 90% of these cases, functional boundaries for language function were found during surgery.
conclusionThis study confirms the feasibility and applicability of monitoring language functions during awake brain surgery when preoperative language deficits are present. Both low-grade and high-grade glioma patients show an overall stable performance on a language comprehension test and an improved performance on a language production test 3 to 6 months after surgery and, therefore, seemed to benefit from cognitive monitoring.
