Hemispherotomy for Drug-Resistant Epilepsy in a Low-Resource Setting: Surgical Outcomes and Quality of Life in 23 Children Treated in a Hybrid Program in Panama.
Article in Pediatric neurosurgery, 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
introductionHemispherotomy is an effective treatment for children with drug-resistant epilepsy (DRE). While hemispherotomy techniques and indications have evolved, access remains predominantly constrained to high-resource settings.
methodsWe performed a retrospective analysis of children who underwent hemispherotomy from 2011 to 2023 by a hybrid team, including local Panamanian and US neurologists, neurosurgeons, and EEG technicians and analyzed surgical, epilepsy, and quality of life (QoL) parameters. Follow-up data were collected according to the International Consortium for Health Outcomes Measurement (ICHOM) guidelines for children with epilepsy.
resultsTwenty-three children underwent hemispherotomy. The median age at surgery was 10 years (range 2-20). The median follow-up time was 6 years (range 1-13). The etiology of DRE included malformations of cortical development in 14 children (60.8%), including 8 (34.8%) with schizencephaly, and secondary causes in 9 children (39.1%). Seizure frequency improved for all 23 children (100%): Engel I was achieved in 15 children (65.2%), Engel II (26.1%) in six children, and Engel III (8.7%) in two children. Patients with seizure freedom had significantly fewer preoperative seizures per day than patients with seizure recurrence. Complications occurred in six children (26.1%): 2 wound infections, 2 meningitis, 1 femoral vein thrombosis, and 1 wound hematoma with return to OR. There were no perioperative mortality and no postoperative hydrocephalus or CSF diversion. QoL-related outcomes were available for 16 children: 16/16 (100%) reported that the surgery was a worthwhile and repeatable choice, 14 (87.5%) reported improved cognitive function, the median QOLCE-16 score was 62.5 ± 21.
conclusionHemispherotomy for DRE in selected children is a safe and effective surgery in a public children's hospital in a low-resource setting. At last follow-up, the majority of children were seizure-free, and all children had decreased seizure frequency. Families reported improved cognitive function, improved QoL and high satisfaction with their decision to pursue this surgery.
