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
A unified view on recovery from supplementary motor area syndrome after glioma resection is lacking. This study retrospectively examined the relationship between motor function, higher brain function, the ability to perform activities of daily living, and social reintegration and the extent of tumor resection in patients who underwent resection of tumors near the supplementary motor area. We assigned 24 consecutive patients into 3 groups according to the depth of tumor resection: resection involving (A) only the supplementary motor area (5 patients); (B) the supplementary motor area and cingulate gyrus (11 patients); and (C) the supplementary motor area, cingulate gyrus, and corpus callosum (8 patients). Motor paralysis, language function, and the ability to perform activities of daily living were evaluated perioperatively and 2 months postoperatively, whereas successful social reintegration was examined retrospectively. In group C, 62% of patients developed severe paralysis after surgery, with slow recovery and delayed ambulation (p = 0.0869). Patients with tumors in the left hemisphere, specifically those extending to the cingulate gyrus and corpus callosum, showed decreased scores for postoperative word recall; however, recovery was observed after 2 months. The Functional Instrumental Measure score, which indicates the activity of daily living ability, showed the largest difference preoperatively and postoperatively in group C. The World Health Organization tumor grade (p = 0.0445) and extent of tumor resection (p = 0.0011) were inversely correlated with social reintegration 6 months postoperatively. Overall, the findings suggest that early social reintegration is influenced by the World Health Organization tumor grade (2021 World Health Organization classification) and the extent of tumor resection.
