[Characteristics of patients with drug-resistant epilepsy in a tertiary hospital].
Article in Revista de neurologia, 2024. 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
introductionDrug-resistant epilepsy has a cumulative incidence between 14 and 20% of patients with epilepsy. It is associated with more comorbidities and with higher healthcare expenditure and impact on quality of life. PATIENTS AND
methodsA retrospective longitudinal descriptive study was performed covering the period from 01/01/2010 to 02/28/2024. All patients with epilepsy seen in the Pediatric Neurology unit of our center were collected and a review of medical records was carried out to collect the characteristics and evolution during the study period. The classification and definitions used were those established by the International League Against Epilepsy.
resultsA total of 325 patients with epilepsy were identified, with a cumulative incidence of DRE of 29%. The most frequent etiology was structural both in all patients with epilepsy (22%), and in drug-resistant epilepsy (36%). A statistically significant association was established between refractoriness and genetic and structural causes, and between having status epilepticus and the development of drug-resistant epilepsy. Seventy-nine percent of patients with drug-resistant epilepsy developed epileptic encephalopathy. The most commonly used antiseizure drug was valproic acid (90%), 19% received a ketogenic diet and 4.2% received epilepsy surgery.
conclusionsIn our setting the incidence of drug-resistant epilepsy is high, more so than previously described. Genetic and structural etiologies are associated with a higher incidence. Having suffered status epilepticus is associated with refractoriness. A higher incidence was observed in patients with defined electroclinical syndromes, probably influenced by epileptic and developmental encephalopathies.
