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

A multifunctional starch-based composite membrane was developed by incorporating self-assembled berberine-oligomeric procyanidins nanoparticles (SBO) loaded with tea tree oil (TTO) into a thermoplastic starch (TPS) matrix. Characterization indicated successful SBO formation and TTO loading (up to 62.36 mg/g), which followed a monolayer adsorption mechanism with pseudo-first-order kinetics. The incorporation of SBO@TTO significantly improved tensile strength and gas barrier properties of the membranes. The composite membranes exhibited excellent pH-responsive color changes and enhanced antioxidant and antibacterial activities. TTO release was sustained and diffusion-controlled, and the membranes exhibited satisfactory in vitro cytocompatibility. TPS/4%SBO@TTO membrane effectively reduced weight loss and softening of cherry tomatoes, showing better performance than air storage and comparable performance to a commercial polyethylene membrane. These results demonstrate the strong application potential of TPS/SBO@TTO membranes as active and intelligent food packaging. The direct migration and preservation performances should be further validated under various storage conditions and for different food products.
