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

objectiveThe systematic use of pulsatile corticosteroid therapy (PCT) in children with drug-resistant epilepsy has been shown to reduce epileptic activity. However, it remains unclear how long this effect will last. The objective of this study was therefore to evaluate the stability of the effect of PCT by assessing the interictal epileptic activity burden (% of electroencephalography (EEG) with interictal epileptic activity, IEA) one year after the end of treatment.

methodsThe final study cohort consisted of 20 children (9 females; mean age 7.6 ± 3.5 years) with various drug-resistant surgically nonremediable epilepsies who underwent systematic treatment with PCT (20 mg/m

resultsIEA burden was significantly reduced after PCT treatment (4.9% [2.4-20.4] vs. .9% [.2-5.5], p = .005, d = -.47) and this effect continued to persist at follow-up (.9% [.2-5.5] vs. 2.7% [.2-7.4], p = .99, d = .02). At time of follow-up, 33.3% patients showed a relapse defined by an increase in IEA burden after an initial decrease of at least 50% through PCT. Fast spindle rate (12-16 Hz) tended to be higher after PCT (1.0 ± .8 vs. 1.6 ± .8, p = .08, d = .59) and remained stable between the end of PCT and follow-up (1.6 ± .8 vs. 1.6 ± .4, p = .98, d = .01). SIGNIFICANCE: Our findings suggest that in the majority of patients, PCT led to long-lasting benefits not only by reducing epileptic activity but also by improving sleep, important for cognitive functions.
