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
objectiveCrossed cerebellar diaschisis is a neuroimaging phenomenon observed in various neurological conditions, including status epilepticus. This systematic review aims to summarize the clinical and radiological characteristics of patients developing crossed cerebellar diaschisis following status epilepticus and to discuss potential pathophysiological mechanisms.
methodsA systematic literature search was conducted using MEDLINE/PubMed, Embase, Web of Science, and CENTRAL from inception to October 2025. Studies reporting crossed cerebellar diaschisis in patients with status epilepticus, confirmed by neuroimaging (MRI, PET, or SPECT), were included. Data on demographics, semiology, etiology, imaging findings, EEG, and outcomes were extracted and synthesized. A spatial analysis of supratentorial MRI abnormalities associated with crossed cerebellar diaschisis was performed in 18 cases with suitable imaging.
resultsSixty patients from 50 studies were included. Mean age was 46.1 years; 50% were female. Convulsive status epilepticus was present in 62% of cases. Etiology was acute in 40%, unknown in 45%. Crossed cerebellar diaschisis was most frequently detected via DWI hyperintensity (55%) and FLAIR/T2 changes (52%). Arterial spin labelling and SPECT often showed hyperperfusion in the acute phase. Spatial mapping of supratentorial MRI abnormalities revealed a predominant involvement of cortical temporo-occipital regions, with minimal subcortical involvement, aligning with known cerebro-cerebellar connectivity patterns. Cerebellar symptoms were rare (5%), but cerebellar atrophy was reported in 7% of cases. Mortality was 10%; 30% recovered completely, while 33% had neurological deficits at discharge. SIGNIFICANCE: Crossed cerebellar diaschisis is a dynamic phenomenon, presenting with both hyper- and hypoperfusion or metabolism, based on the timing and severity of status epilepticus. It may result from increased inhibitory cerebellar activity during seizures, followed by metabolic exhaustion and Purkinje cell loss. Although often clinically silent, it might lead to long-term cerebellar atrophy and neurological sequelae.
