Evaluation of the International League Against Epilepsy 1981, 1989, and 2017 classifications of seizure semiology and etiology in a population-based cohort of children and adults with epilepsy.
Article in Epilepsia open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
objectiveThe International League Against Epilepsy (ILAE) has revised the classification of epilepsies and seizures on several occasions since the original classification published in 1964. It is unclear if these changes have impacted the characterization of epilepsy, including the clinical validity of seizure semiology or epilepsy outcomes in resource-poor areas. We aim to address this important knowledge gap.
methodsWe reviewed the clinical seizure semiology and etiological data of 483 persons with epilepsy identified from a population-based survey in rural Kenya. The seizure semiology and etiological data were classified using the 1981 (for seizures) and 1989 (for epilepsy) ILAE criteria and then reclassified according to the ILAE-2017 criteria. Logistic regression models adjusted for potential confounders were used to measure the associations between the seizure semiology and different clinical and electroencephalographic features of epilepsy.
resultsFocal (formerly localization-related) and generalized epilepsies were lower in ILAE-2017 (56% and 29%) than that of ILAE-1989 (61% and 34%), P < .001 and P < .001. Combined focal and generalized epilepsy type in ILAE-2017 accounted for 11% of epilepsies. Individual seizure types were statistically similar in both ILAE-1981 and 2017. New classification categories in ILAE-2017 such as unknown seizures and epilepsies were identified, and the proportions were similar to the unclassified category in ILAE-1989, 6% and 5%, respectively. The most common causes of epilepsy were symptomatic (76%) in the ILAE-1989 criteria, with infectious (45%) and structural (36%) causes were highest in the ILAE-2017 criteria. SIGNIFICANCE: Our study confirms that the two ILAE classification schemes are broadly consistent, but the introduction of the combined onset seizure category in ILAE-2017 significantly reduces the proportion of mutually exclusive focal and generalized seizures. The comprehensive classification of etiology categories in ILAE-2017 will facilitate appropriate treatment and improve prognosis.
