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

The present use of ocular activity to enhance the temporal resolution of the classification of sleep onset period (SOP) allowed to reveal an increase in the power of oscillations in the BOLD signal at 0.05 Hz in the brain, particularly in sensory cortices, as soon as the first signs of drowsiness. These changes were evident in the "likely drowsy" state of SOP, representing early sleep-related vigilance fluctuations, often encountered even during activities like driving. Our findings show changes in the BOLD signal even before conventional indicators of sleep onset.
