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

Alzheimer's disease (AD) is a neurodegenerative disorder marked by the accumulation of β-amyloid (Aβ) peptides, which disrupt neuronal homeostasis through their neurotoxic effects. Aβ aggregates interfere with synaptic function by interacting with nicotinic acetylcholine receptors (nAChRs), particularly the α7 subtype, thereby impairing cholinergic signaling, which is crucial for cognition and memory. Pharmacological advancements have identified Positive Allosteric Modulators (PAMs) as promising therapeutic agents to counteract Aβ neurotoxicity. PAMs enhance nAChR activity by binding to allosteric sites, thereby reducing Aβ-induced neurotoxicity without competing with acetylcholine. This study evaluates 3-((6-(phenylethynyl)pyridine-3-yl)oxy)quinuclidine (
