Peri-ictal signal changes in seven patients with status epilepticus: interesting MRI observations.
Article in Neuroradiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
introductionTransient peri-ictal changes on imaging had been described following status epilepticus (SE), but its cause is not very well understood. We analyzed the magnetic resonance imaging (MRI) findings in SE patients in order to elucidate such changes including peri-ictal signal. MATERIALS AND
methodsThis prospective study involved 34 patients (M/F 23:11, mean age 25.8 +/- 17.2 years) who experienced SE. MRI was performed during or within 96 h of cessation of seizures. Twenty-five patients had generalized convulsive status epilectus (GCSE; ten secondary GCSE and 15 primary GCSE). Seven patients had epilepsia partialis continua and two patients non-convulsive SE. Eight patients had a history of seizures and three patients previous SE. The mean duration of SE prior to MRI was 89.2 +/- 105.3 h (range 2-360 h). MRI provided diagnosis in 17 patients, and in 13 patients, no structural cause was identified.
resultsPeri-ictal focal signal changes with restricted diffusion on apparent diffusion coefficient maps were present in seven (20.6%) patients with SE (generalized convulsive, three; partial, three; non-convulsive, one). The changes were observed when MRI was performed during SE in 3/10 (30%) patients, or within 24 h in 1/7 (14.3%), 48 h in 1/5 (20%), 72 h in 1/6 (16.7%), or 96 h in 1/6 (16.7%) patients after cessation of seizures. Repeat MRI revealed disappearance of signal changes in two patients.
conclusionsPeri-ictal MR changes with restricted diffusion appear to be an effect rather than the cause of SE.
