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 developed biodegradable levan-chitosan composite films for beef filet packaging, optimizing their functional properties and assessing their efficacy in food preservation. Films were prepared via solution casting using varying levan-chitosan ratios (100:0, 75:25, 50:50, 25:75, 0:100) with glycerol (30%) as a plasticizer. The L25:C75 formulation exhibited superior mechanical properties (tensile strength: 15.43 ± 0.04 MPa; elongation at break: 35.37 ± 1.12%) and high-water solubility (46.64 ± 0.37%). FTIR analysis confirmed intermolecular interactions between levan and chitosan. The films demonstrated strong antioxidant activity (91% ABTS•+ inhibition) and broad-spectrum antibacterial effects, with inhibition zones of 18 ± 0.30 mm against
