Incidence and clinical predictors of epilepsy after febrile seizures in children: A prospective cohort study in Vietnam.
Article in Epilepsia open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveFebrile seizures (FS) are common and usually self-limited, yet a subset of children develop epilepsy. Early risk stratification remains challenging, particularly in resource-limited settings with limited access to long-term neurologic follow-up. We aimed to estimate the incidence and identify the most robust predictors of epilepsy following FS in children.
methodsIn this prospective cohort study at Children's Hospital 2 (Ho Chi Minh City, Vietnam), 631 children aged 1 month to 6 years with first FS were enrolled (March 2023-March 2024) and followed through July 2025. Children with any history of seizures prior to the index FS were excluded. Epilepsy was defined per the International League Against Epilepsy (ILAE) 2014 criteria. Predictor selection used clinical reasoning and Bayesian Model Averaging (BMA), followed by multivariable Cox regression. Discrimination was evaluated using Harrell's C-index and time-dependent AUC; internal validation was performed with bootstrap resampling.
resultsOver a median follow-up of 2.0 years, 35 children (5.5%) developed epilepsy, corresponding to an incidence of 29 per 1000 person-years. After BMA, four independent predictors were retained: neurodevelopmental delay (HR = 8.78), family history of epilepsy (HR = 2.66), focal seizures (HR = 3.23), and each additional FS recurrence (HR = 1.50). The predictor set showed strong discrimination (C-index: 0.87; AUC at 24 months: 0.89 with 95% CI: 0.82, 0.95). SIGNIFICANCE: This parsimonious set of clinical predictors may support early counseling and targeted follow-up of children with FS, especially where pediatric neurology resources are limited. Model development and validation are ongoing. PLAIN LANGUAGE SUMMARY: We followed 631 children after their first febrile seizure to see who might later develop epilepsy. About 5.5% of children developed epilepsy within 2 years. Children with developmental delay, focal seizures, a family history of epilepsy, or repeated FS were at higher risk. Using these four simple factors may help doctors give families clearer advice and closer follow-up, especially where access to pediatric neurologists is limited.
