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
The synergistic antimicrobial and antioxidant effects of glutaric acid (GLA) with sorbic acid (SoA) or sodium bisulphite (SoB) were evaluated to determine their optimal concentrations and ratios for maximum efficacy. The results revealed that these combinations exhibited strong antimicrobial properties, with GLA-SoB also demonstrating significant antioxidant activity. These findings were consistent across both in vitro and food model (using salmon) evaluations. The combinations effectively extended shelf life and preserved freshness when applied to sliced and minced salmon. GLA, GLA-SoA (2:1), and GLA-SoB (1:2) were particularly effective in maintaining color, stabilizing pH and moisture levels, and reducing spoilage markers such as total volatile base nitrogen (TVB-N), peroxide value (POV), thiobarbituric acid (TBA) levels, and microbial counts. This study highlights the comparable effectiveness of GLA-SoB (1:2) and GLA-SoA (2:1) in inhibiting microbial growth and extending the shelf life of salmon under refrigerated conditions. Both combinations showed dose-dependent efficacy in preserving quality and safety, making them promising candidates for enhancing the storage stability of salmon products.
