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

The generation of β‑amyloid protein (Aβ) is considered a key step in the pathogenesis of Alzheimer's disease (AD) and the regulation of its production is an important therapeutic strategy. It was hypothesized in the present study that Nogo‑A may be involved in AD and may regulate the generation of Aβ. Nogo‑A is known to act as a major inhibitor of neuron regeneration in the adult central nervous system. A recent study indicated that Nogo‑A is associated with AD; however, the underlying effect and molecular mechanisms remain largely elusive. In the present study, the potential effects of Nogo‑A on AD were investigated. ELISA was used to detect the levels of Aβ, enzymatic activity detection kits were used to determine the activity of secretase enzymes in amyloid precursor protein (APP) metabolism, and western blot analysis was used to detect the expression levels of proteins associated with the APP processing and Nogo‑A/Nogo‑66 receptor (NgR) signaling pathways. The results revealed that Nogo‑66, the major inhibitory region of Nogo‑A, promoted neuronal Aβ secretion by increasing the activity of β‑secretase 1 via the NgR/Rho‑associated coiled‑coil containing kinases pathway in a dose‑dependent manner. The present data suggested that Nogo‑A may facilitate the onset and development of AD by promoting Aβ secretion, providing information on a potential novel target for AD therapy.
