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

This study aimed to synthesize silver nanoparticle-embedded casein nanocomposites (AgNP@CN) and incorporated them into zein (ZN)-derived bioplastic films to enhance their functional properties. The shape, size/dimension, morphology, surface charge, and surface chemistry of AgNP@CN were investigated. After forming AgNP@CN-functionalized ZN bioplastic films (AgNP@CN-ZN), the bioplastic films were characterized. Incorporation of AgNP@CN improved the mechanical properties, thermal stability, surface hydrophobicity, and UV resistance of ZN films. Additionally, the water vapor barrier properties of AgNP@CN-ZN bioplastic films were comparable to or superior to those of conventional plastics. In terms of food packaging, the AgNP@CN-ZN films effectively reduced weight loss and enzymatic browning in banana peels as a food model. Accordingly, the silver content in banana pulp wrapped with AgNP@CN-ZN film was 5.57 × 10
