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

Abundant clinical and preclinical evidence demonstrates that sleep and pain have bidirectional interactions. Sleep loss enhances pain perception and pain disrupts sleep. However, the exact neurobiological mechanisms through which sleep loss alters pain remain poorly understood. The preoptic area of the hypothalamus is crucial for the regulation of sleep onset and sleep homeostasis, and it innervates downstream regions that regulate arousal states and pain. Adenosine neurotransmission in the preoptic region plays a key role in the sleep homeostatic response following prolonged wakefulness or sleep deprivation. Previous studies showed that pharmacologically blocking adenosine A
