A Standardized Approach to MRI-Guided Stereotactic Laser Corpus Callosotomy: Technical Description and Pediatric Case Series.

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 AND
objectivesCorpus callosotomy is an effective procedure approach for treating medication-resistant drop seizures, which pose a significant challenge in patients with epilepsy. Laser interstitial thermal therapy offers an alternative to open surgery for performing corpus callosotomy that may limit approach-related comorbidities. Practices vary regarding the number of laser filaments used and staging; outcome data for pediatric patients remain relatively limited.
methodsWe illustrate a set of 4 standardized trajectories for performing MRI-guided stereotactic laser corpus callosotomy (SLCC). For this retrospective cohort study in a pediatric neurosurgery practice, the medical records and imaging were reviewed for 10 consecutive patients who had medication-refractory drop seizures and underwent SLCC. Data collected and analyzed included patient and epilepsy characteristics, procedural details, surgical approaches, and clinical follow-up results.
resultsOver 2 years, complete, single-stage SLCC was performed in 8 patients, and posterior completion SLCC was performed in 2 patients who had previously had open anterior corpus callosotomy. Four laser fibers were used in four-eighth complete SLCC, and 3 fibers were used in four-eighth complete SLCC. Seven of 10 patients were discharged from the hospital on postoperative day 1, with only 1 requiring a maximum stay of 6 days. Five of 9 evaluable patients reported no drop seizures at the last clinical follow-up. In the other 4 patients, 1 experienced them only rarely, another experienced less than 25% preoperative frequency, and the remaining 2 had less than a 50% improvement. In addition, improvement in other seizure types exceeded 50% in 8 of 9 patients. Notably, no perioperative or postoperative complications were observed, nor were there any sustained neurological deficits reported.
conclusionComplete SLCC can be safely and effectively performed in pediatric patients. It is comparable in effectiveness with open surgery but has lower complication rates and shorter hospitalization.
