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

Endogenous brain activity plays a key role during sleep, facilitating important functions like learning and memory consolidation. Its precise mechanisms are not yet understood. Recent functional MRI (fMRI) research has revealed structured multi-second waves that travel across the cortex along a hierarchical functional gradient during wakefulness. However, how these waves are modulated across different sleep stages remains unclear. Here, we present compelling evidence of significant changes in both the frequency and spatiotemporal patterns of these waves across sleep stages. Notably, during rapid eye movement (REM) sleep, we observed a predominance of propagations from sensory/motor areas to higher-order networks. These patterns were distinct from other sleep stages, with key regions like the thalamus, pons, and visual cortex-linked to PGO waves-activating at the earliest phase of waves. Similar to PGO waves, these fMRI waves were coupled with REM activity, suggesting their potential role in supporting memory consolidation and learning processes.
