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

backgroundDeep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT-DBS) has demonstrated potential in reducing seizure frequency (SF) in patients with drug-resistant epilepsy (DRE). This multicenter retrospective study aimed to comprehensively evaluate the long-term effects of ANT-DBS on seizure reduction and neuropsychological outcomes, as well as to identify prognostic factors associated with postoperative efficacy.

methodsWe retrospectively analyzed data from DRE patients who underwent ANT-DBS across three epilepsy centers between July 2019 and December 2022. SF, responder rate, neuropsychological outcomes, and quality of life (QoL) were assessed using seizure diaries and standardized rating scales at baseline and annual follow-up. Univariate and multivariate regression analyses were performed to identify predictors of postoperative SF reduction.

resultsA total of 40 patients were included, with a mean age at surgery of 28.6 ± 11.1 years. The average monthly SF decreased from 15 at baseline to 6.5 at the 5-year follow-up (a 56.7% reduction, p < 0.001), with a responder rate of 62.5%. Therapeutic effect was most pronounced within the first 24 months after implantation. The Liverpool Seizure Severity Scale (LSSS) scores improved from 26.7 ± 5.2 to 17.9 ± 8.6 (p < 0.001). Mood conditions (measured by the Hamilton Depression and Anxiety Rating Scales) improved from baseline to the final follow-up, while cognitive status remained stable. QoL also improved significantly, particularly in Overall QoL, Emotional Well-being, Energy/Fatigue and Social Functioning. Multivariate logistic regression identified temporal lobe seizures (OR 8.3, p = 0.022) and stimulation amplitude (OR 4.2, p = 0.034) as independent predictors of responder status following DBS implantation. Multivariate linear regression identified baseline LSSS scores (standardized β: 3.5, p = 0.016) and temporal lobe seizures (standardized β 35.4, p = 0.024) as independent predictors of SF reduction.

conclusionsANT-DBS significantly reduces SF in patients with DRE and shows stable long-term efficacy. The seizure onset zone, preoperative seizure severity and stimulation amplitude are critical predictors of postoperative outcomes, providing valuable information for optimal patient selection for this intervention.
