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.
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
Gastric cancer (GC) remains a major global health burden, with limited effective therapies and poor prognosis. Quercetin (Que), a natural flavonoid, exhibits anticancer activity but suffers from poor water solubility, limited oral bioavailability, and rapid metabolic clearance, which severely restrict its clinical translation. These pharmacokinetic limitations necessitate an efficient delivery system capable of stabilizing Que in circulation and enabling tumor-specific release. To address these limitations, a zeolitic imidazolate framework-8 (ZIF-8) was developed based on nanoparticles that encapsulate Que (ZIF-8@Que), enabling high loading efficiency and pH-responsive release. ZIF-8@Que was efficiently internalized by GC cells and localized within lysosomes, where the acidic environment accelerated drug release. This process coincided with marked reactive oxygen species (ROS) generation, leading to mitochondrial membrane depolarization, ATP depletion, and ultrastructural damage. Cellular analyses further revealed features consistent with pyroptotic cell death, including lactate dehydrogenase (LDH) release, increased staining for cleaved caspase-1 and cleaved gasdermin-D (GSDMD), and enhanced TUNEL-positive signals. Compared with free Que or empty ZIF-8, ZIF-8@Que demonstrated stronger inhibition of proliferation, migration, and invasion
