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
backgroundRedo awake surgery is ideal for recurrent malignant gliomas in the language-dominant hemisphere, but it may not always be optimal because of inadequate awake mapping. In this report, the authors describe a case of recurrent language-dominant frontal glioma in which a super-selective Wada (ssWada) test and super-selective cone-beam CT angiography (ssCBCTA) enabled successful tumor removal under general anesthesia after awake surgery. OBSERVATIONS: A woman in her 30s underwent awake surgery for left frontal glioma recurrence 2 years after the initial resection. Three years after another recurrence, the ssWada test and ssCBCTA revealed that the tumor-supplying artery did not perfuse the functional cortex, allowing safe and maximal resection under general anesthesia. Postoperatively, she had mild motor aphasia but recovered quickly with minimal sequelae. LESSONS: The combined use of the ssWada test and ssCBCTA enables precise preoperative language mapping and safe tumor resection. Originally developed for epilepsy surgery, the ssWada test is valuable for functional mapping and, when paired with ssCBCTA, provides a 3D understanding of the lesions. This combination serves as a critical preoperative tool for tumors in the language-dominant hemisphere. https://thejns.org/doi/10.3171/CASE25384.
