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
Epigallocatechin gallate (EGCG) represents the key phenolic compound in green tea, which has been verified to possess various biological effects but suffers from low stability and poor bioavailability. To address these issues, EGCG-loaded nanoliposomes (ELs) were screened and prepared using an ethanol injection-calcium acetate gradient (EtOH-CAG) method. An encapsulation efficiency of 94.61% was achieved, involving a particle size of 118.6 nm and a polydispersity index (PDI) of 0.23. Via layer-by-layer assembly, nanoliposomes modified with either ε-polylysine (ε-PL) monolayer (ELP) or ε-polylysine/sodium alginate (SA) bilayer (ELPA) exhibited substantially improved stability. Moreover, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and thermal analysis confirmed the effective loading of EGCG and the successful decoration of ε-PL and SA. Molecular docking analyses of dual ligands further characterized the surface modification mechanism, which was primarily mediated by hydrogen bonding and electrostatic interactions. ELPA maintained robust stability under conditions including 200 mM salt concentration, a pH range of 4-10, temperatures up to 55 °C, and a 25-day storage duration. The modified systems showed considerably enhanced cellular uptake without causing cytotoxicity. Collectively, the developed ε-PL/SA bilayer nanoliposomes offer an eco-friendly, efficient strategy to enhance EGCG stability and in vitro bioavailability in functional food applications.
