Temporal Trends in Hippocampal Sclerosis Surgery: An Observational Study From a Tertiary Epilepsy Centre.
Observational study in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTemporal lobe epilepsy with hippocampal sclerosis (HS) is a surgically remediable syndrome. We determined temporal trends in the prevalence of hippocampal sclerosis surgeries and related factors.
methodsWe analysed a prospective cohort of adults who underwent epilepsy surgery at the NHNN, London, between 1990 and 2019. HS group was compared with other pathologies. Demographics, surgical trends for HS and associations with sex, age, prior neurological insults and febrile seizures were analysed. Temporal trends were assessed by one-way or Welch ANOVA, with post hoc analysis. Surgery latency over three decades was evaluated with the Kruskal-Wallis H test, using Dunn's procedure for pairwise comparisons. Chi-squared analyses examined associations with sex, age at operation, febrile seizures, and between resection side and handedness.
resultsOf 1069 people operated, 586 had hippocampal sclerosis. After increasing, surgeries declined in the last decade (from 322 to 131), as did the number of people with hippocampal sclerosis and a history of childhood febrile seizures (from 87 to 23). The median interval from epilepsy onset to surgery increased from 22 to 24 and 27 years over each decade. Female sex and febrile seizures were associated with pathology (HS vs. non-HS) but not age at surgery, previous neurological insults, or the resection side and handedness. DISCUSSION: Our study confirms the decline in hippocampal surgeries. This trend may be due to changes in the syndrome's natural history, possibly from improved paediatric care, and an increase in complex cases. The impact of delayed referrals, surgical risk fears and newer anti-seizure medications remains unclear.
