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

introductionThe sleep-wake cycle and circadian rhythm disturbances are common in Alzheimer's disease (AD). However, it is not known if exercise has any benefit for the sleep disorders in AD.

methodsWe conducted a 2-month voluntary wheel running (VWR) exercise (Ex) in an animal model of AD (APP

resultsAfter VWR exercise in the AD mice, the rapid eye movement sleep was increased by 89%. The levels of circadian clock genes were significantly changed (brain and muscle arnt-like protein 1 [BMAL1] and retinoic acid receptor-related orphan receptorsα [RORα] reduced by 45.7% and 36.4%, reverse erythroblastosis virusα (REV-ERBα) increased by 119%) in the SCN by immunofluorescence staining, with the mRNA levels were markedly altered (Bmal1 and Rorα decreased by 57% and 68%, Rev-erbα elevated by 79%) in the hypothalamus at Zeitgeber Time 1; phospho-tau 231 (p-tau231) was reduced by 35%, whereas vesicular GABA transporter (VGAT) was elevated by 38.7% in the SCN. In addition, ionized calcium binding adapter molecude 1 (Iba1), glial fibrillary acidic protein (GFAP), amyloid β (Aβ), and p-tau231 were significantly reduced in the hippocampus and cortex. DISCUSSION: Our results demonstrate that VWR exercise improves sleep disorders, cognitive deficits, and neuropathology in AD mice. HIGHLIGHTS: Voluntary wheel running (VWR) exercise improves the behavioral circadian rhythm disorder and sleep structure disturbance in Alzheimer's disease (AD) mice. After VWR exercise, there is a significant change in the expression levels of circadian clock genes, and a remarkable reduction of tau phosphorylation and axonal damage in the γ-aminobutyric acid (GABA)ergic neurons in the suprachiasmatic nucleus (SCN). The levels of beta-site amyloid precurson protein cleaving enzyme 1 (BACE1) and glycogen synthase kinase-3β (GSK3β) are reduced in the hypothalamus after VWR exercise in AD mice. Furthermore, VWR exercise attenuates cognitive deficits, neuroinflammation, amyloid beta (Aβ), and phospho-tau protein accumulation in the hippocampus and cortex.
