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

Ischemic retinal damage is the most common cause of severe vision impairment and blindness. Anti-vascular endothelial growth factor (anti-VEGF) agents have transformed the treatment of retinal ischemic disorders and have become the cornerstone therapy for these conditions. Nonetheless, the risk for systemic and ocular adverse effects necessitates careful consideration. Meanwhile, the therapeutic potential of natural compounds for ischemic retinal injury is increasingly attracting attention. In this study, piperine (PIP), a natural compound derived from pepper, was found to reduce apoptosis by reducing the severity of retinal and optic nerve ischemic damage. However, the precise pharmacological mechanisms of PIP are yet to be fully elucidated. Molecular docking (MD) studies, MD simulations, and surface plasmon resonance experiments were conducted to determine the molecular targets of PIP. Our data revealed that PIP can bind to apurinic/apyrimidinic endonuclease 1 (APE1), thereby inhibiting apoptosis by decreasing the expression of caspase-9 and caspase-3 and regulating the mitochondrial pathway. In summary, PIP may directly targets the APE1 protein and further regulates the caspase-9/caspase-3 axis to provide neuroprotection against ischemic retinal injury.
