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

aimsTo evaluate the therapeutic effects of NAP2, a novel NgR1 antagonist peptide, on Alzheimer's disease (AD) pathology and to determine whether inhibition of the Nogo-A/NgR1/ROCK signaling axis can ameliorate neurodegenerative alterations in APP/PS1 mice.

methodsAPP/PS1 transgenic mice received a three-month NAP2 intervention. Cognitive performance was assessed using standard learning and memory tests. Amyloid-β plaque burden, dendritic spine density, tau phosphorylation, and Aβ42 levels were examined by histological and biochemical analyses. Mitochondrial function and downstream ROCK signaling activity were also evaluated.

resultsNAP2 treatment significantly improved cognitive performance in APP/PS1 mice. NAP2 reduced amyloid-β plaque deposition, decreased Aβ42 expression, and increased hippocampal dendritic spine density. Tau hyperphosphorylation was notably attenuated. In addition, NAP2 alleviated Aβ42-induced mitochondrial dysfunction. Mechanistic studies revealed that NAP2 interfered with ROCK signaling downstream of Nogo-A.

conclusionNAP2 ameliorates multiple AD-related pathological features, an effect accompanied by the inhibition of the Nogo-A/NgR1/ROCK pathway. These findings highlight the therapeutic potential of NAP2 to enhance resilience against Alzheimer's disease pathology.
