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

The increasing demand for sustainable and active food packaging materials to extend the shelf life of perishable products has driven the exploration of bio-derived nanomaterials. This study explores the development of biogenic carbon quantum dots (CQDs) derived from lactic acid bacteria (LAB) metabolites as a sustainable approach for active food packaging. CQDs were synthesized via a hydrothermal process and incorporated into carrageenan-based films to develop multifunctional LAB-M/CQD films. The films exhibited significant antibacterial activity, with inhibition zones of 4.14 cm for Escherichia coli, 2.78 cm for Bacillus cereus, and 2.61 cm for Staphylococcus aureus. The antioxidant activity, determined using the DPPH assay, reached a maximum of 97.8% in films containing 3% CQDs, showing a concentration-dependent increase. Mechanical analysis revealed enhanced stiffness, with Young's modulus increasing from 4.36 to 30.97 MPa and tensile strength improving from 1.09 MPa (control) to 1.86 MPa at 3% CQD. However, elongation at break decreased from 17.24% to 6.57%, indicating reduced flexibility. The 3% CQD film demonstrated an optimal balance between strength and functional performance. Barrier analysis showed a reduction in water vapour transmission rate (WVTR) from 506.84 to 446.57 g/m
