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

Epileptic seizures and interictal epileptiform discharges are strongly influenced by sleep and circadian rhythms. However, human data on the effect of sleep on neuronal behaviour during interictal activity have been lacking. We analysed EEG from eight epileptic patients implanted with macro and micro electrodes in mesial temporal structures. Sleep staging was performed on polysomnography and video-EEG. Automated detection identified thousands of interictal epileptiform discharges per patient. Both their rate and amplitude increased with deeper stages of non-rapid eye movement sleep. Single- and multi-unit firing rates were often temporally coupled with local field potentials, exhibiting increased firing during the spike and decreased activity during the following slow wave. These time-locked firing rate modulations were shown to increase during deeper stages of non-rapid eye movement sleep. Furthermore, neuronal background activity showed a decrease in firing rate, bursting and regularity with deeper stages of non-rapid eye movement sleep.
