Predicting postoperative motor outcomes in the surgical management of Rolandic focal cortical dysplasia: the role of glucose metabolism.
Article in BMC medicine, 2025. 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
backgroundThis study aimed to explore the predictive value of
methodsWe conducted a retrospective analysis of 62 patients with FCD who underwent resective surgery in the Rolandic area. Of these, 15 patients underwent task-based functional magnetic resonance imaging (fMRI). Motor functional reorganization and its relationship with PET metabolism were analyzed. Patients were classified into deficit and non-deficit groups according to their postoperative motor function status. PET metabolism in the resected motor cortex was compared between the two groups, and its correlation with postoperative muscle strength was further evaluated in the deficit group.
resultsAmong the 15 patients who underwent fMRI evaluation, the extent of motor reorganization was negatively correlated with PET metabolism (P = 0.0006). PET analysis revealed significantly higher PET metabolic T-values in the resected Rolandic cortex of the motor deficit group compared to the non-deficit group (P = 0.0004). Furthermore, within the deficit group, PET metabolic T-values were negatively correlated with postoperative muscle strength (P = 0.017). The prediction model for postoperative motor function, demonstrated strong performance in cross-validation, with an area under the curve (AUC) of 0.82, a sensitivity of 83%, and a specificity of 76%.
