Chronic sleep restriction activates complement and coagulation cascades: a molecular link to accelerated brain aging.

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.
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
Chronic sleep insufficiency is prevalent in modern society and has been associated with age-related neurodegenerative diseases. Sleep loss accelerates neurodegeneration in animal models. Here, we study whether chronic sleep curtailment leads to brain aging in wild-type mice without a genetic predisposition. We simulated modern-day conditions of restricted sleep and compared the brain (cortex) proteome of young sleep-restricted animals with different aged control groups. We report the alteration of 145 proteins related to sleep and 1275 related to age, with 71 proteins common between them. Through pathway analysis of proteins common to sleep restriction and aging, we discovered that the complement and coagulation cascade pathways were enriched by alterations of complement component 3 (C3), fibrinogen alpha and beta chain (FGA and FGB). This is the first study indicating the possible role of the complement and coagulation pathways in brain aging by chronic sleep restriction (CSR) in mice.
