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

Packaging films based on natural biopolymers often suffer from inadequate barrier and mechanical properties. To address these challenges, multilayer films have emerged as potential solutions. In this study, we prepared bilayer films using bitter vetch seed protein (BVSP) and polylactic acid (PLA). The barriers, mechanical, physical, chemical, thermal and morphological properties of the prepared films were evaluated. The bilayer films exhibited robust adhesion between the BVSP and PLA layers without any chemical modification or additional components. This physical interaction between the layers contributed to the overall film properties. The addition of the PLA layer to BVSP films led to reduced solubility and moisture content in the bilayer films compared to pure BVSP films. The bilayer films demonstrated good tensile strength, ranging from 13.46 to 15.51 MPa, surpassing the BVSP films (ranging from 5.66 to 6.25 MPa). Additionally, the bilayer films exhibited better elongation at break, ranging from 17.91 % to 27.68 %, compared to pure PLA films (ranging from 14.95 % to 23.28 %). The bilayer films exhibited reduced water vapor permeability (WVP), ranging from 1.40 × 10⁻
