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

objectiveTo assess and compare the detection rates of peri-ictal abnormalities using magnetic resonance imaging (MRI) and computed tomography perfusion (CTP) in patients with non-convulsive status epilepticus (NCSE).

methodsWe conducted a systematic literature search in five databases up to February 2025. Studies reporting peri-ictal MRI abnormalities (PMAs) or cerebral perfusion abnormalities (CPAs) in patients with NCSE were included. Meta-analyses of proportions were performed using a random-effects model. Subgroup analyses and meta-regression were used to compare detection rates across imaging modalities.

resultsNineteen studies were included (15 MRI, 4 CTP), comprising 562 patients for MRI and 72 for CTP. The pooled detection rate of peri-ictal abnormalities was 50.0% (95% confidence interval [CI]: 34.0%-65.0%) for MRI and 79.3% (95% CI: 54.3%-92.5%) for CTP. Among the MRI modalities, arterial spin labeling (ASL) demonstrated the highest detection rate at 88.8% (95% CI: 32.9%-99.2%). CTP showed a significantly higher detection rate than MRI (χ

conclusionsCTP demonstrates a higher detection rate than conventional MRI for peri-ictal abnormalities in patients with NCSE, supporting its utility in rapid diagnosis and differential workup. Among MRI sequences, ASL showed the highest detection rates, highlighting its potential role in the diagnostic assessment of NCSE. Although MRI remains essential for clarifying etiology, its effectiveness in detecting PMA is highly dependent on the sequences used.
