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

aimStatus epilepticus (SE) is a life-threatening neurological emergency. There is insufficient evidence regarding which antiepileptic therapy is most effective in patients with benzodiazepine-refractory convulsive SE. Therefore, this study aimed to evaluate intravenous phenytoin (PHT) and other intravenous antiepileptic medications for SE.

methodsWe searched PubMed, the Cochrane Central Register of Controlled Trials, and Igaku Chuo Zasshi for published randomized controlled trials (RCTs) in humans up to August 2019. We compared outcomes between intravenous PHT and other intravenous medications. The important primary composite outcomes were the successful clinical cessation of seizures, mortality, and neurological outcomes at discharge. The reliability of the level of evidence for each outcome was compared using the Grading of Recommendations Assessment, Development, and Evaluation approach.

resultsA total of 1,103 studies were identified from the databases, and 10 RCTs were included in the analysis. The ratio of successful clinical seizure cessation was significantly lower (risk ratio [RR] 0.89; 95% confidence interval [CI], 0.82-0.97) for patients treated with intravenous PHT than with other medications. When we compared mortality and neurological outcomes at discharge, we observed no significant differences between patients treated with PHT and those treated with other medications. The RRs were 1.07 (95% CI, 0.55-2.08) and 0.91 (95% CI, 0.72-1.15) for mortality and neurological outcomes at discharge, respectively.

conclusionsOur findings showed that intravenous PHT was significantly inferior to other medications in terms of the cessation of seizures. No significant differences were observed in mortality or neurological outcomes between PHT and other medications.
