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

We evaluated factors possibly influencing serum concentrations of levetiracetam (LEV-SC). The study included 163 patients with epilepsy (91 men, 72 women; mean age 39.6 years). The duration of treatment on first analysis was 226 days; the mean daily dose amounted to 2,434 mg. In each patient between one and seven measurements were carried out (mean 2.2). LEV-SC significantly depended on daily dosage and the interval between the time the medication was taken and the time of blood extraction. A marked drop in LEV-SC was observed 4-5 h following ingestion. Carbamazepine, oxcarbazepine and clobazam reduced LEV-SC, whereas valproate elevated LEV-SC significantly. When assessing evaluation of compliance these factors have to be taken into consideration when comparing intraindividual LEV-SC.
