1 · What the graph read from it

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.

2 · The registry

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

objectiveFor mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE with HS), laser interstitial thermal therapy has recently been increasingly used. At our institute, however, selective amygdalohippocampectomy by a trans-anterior T1 subpial approach (trans-anterior T1 SAH) has been used for MTLE with HS. Here, we examined the seizure, neuropsychological, and quality of life (QOL) outcomes after trans-anterior T1 SAH.

methodsOne hundred patients with MTLE with HS who underwent trans-anterior T1 SAH and were followed for at least 1 year after surgery were included. Seizure outcomes, intelligence and memory, visual field changes evaluated by perimetry, and QOL were investigated.

resultsSeizure-free outcome (Engel class I) at the latest follow-up (mean 4.6 years) was achieved in 88/100 (88%) patients. Only 1 of 100 patients underwent intracranial EEG. Postoperative contralateral upper quadrantanopia was detected in only 15/73 (21%) of patients. Significant improvements in full-scale IQ, verbal IQ, and performance IQ, as examined by the Wechsler Adult Intelligence Scale-III, were seen in both the language-dominant-side surgery and the language-nondominant-side surgery groups. In patients who underwent language-dominant-side SAH, significant declines in general memory and verbal memory scores on the Wechsler memory scale - revised edition were observed at a group level. Significant improvement in attention/concentration was seen regardless of the surgical side. QOL analysis revealed that approximately 30% of patients felt their memory declined after surgery; however, half of the patients felt that being free to go out and become employed was an advantage, and about 90% of patients were satisfied with their surgical treatment. SIGNIFICANCE: Trans-anterior T1 SAH led to favorable seizure outcomes in about 90% of patients with MTLE with HS. Most patients were pleased with their surgery. In patients with MTLE with HS, the preferred surgical strategy should still be SAH.
