Precision in long-term language evaluation after awake brain tumor surgery.

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: Language deficits caused by gliomas can persist beyond the short term, and should not be overlooked due to their influence on a patient's quality of life. The aim of this study was to investigate language impairments and long-term outcome after awake surgery. Methods: The Diagnostic Instrument for Mild Aphasia (DIMA) and traditional language tests were administered preoperatively (T1; Results: Preoperative deficits were found with DIMA at the level of lexico-syntax in Group 1 in both hemispheres and at the level of phonology and lexico-syntax in Group 2. With traditional language tests, preoperative deficits were detected at the level of word retrieval and verbal fluency in all groups. Only DIMA revealed long-term mild language impairments, which were observed at the phonological and semantic level in patients with left-hemispheric tumors, and at the lexico-syntactic level in those with right-hemispheric tumors. Conclusions: In this cohort, mild language impairments were noted long-term with DIMA across different linguistic levels, irrespective of hemispheric tumor location. Alongside the traditional language tests, DIMA represents a valuable addition for the diagnostic evaluation of language impairments in patients with gliomas.
