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
Biosurfactants are increasingly recognized for their versatile applications across industries, including bioremediation and pharmaceuticals. Among these, lipopeptides, produced notably by Bacillus species, demonstrate promising surface activity and biocompatibility. This study investigates the toxicity of lipopeptides biosurfactants derived from the AF_3B strain of Bacillus velezensis. The research delves into the production of lipopeptides biosurfactants from AF_3B and their characterization through antibacterial bioassays, revealing a significant inhibition of various bacterial strains. In vitro assays demonstrate the ability of lipopeptides biosurfactants to suppress the growth of key mycotoxigenic fungi (Aspergillus niger and Fusarium oxysporum) maximum to 86%, confirming their potential as a biological control. In ovo toxicity is assessed by injecting fertile chicken embryos with varying doses (30, 15, 7.5, 3.75, and 1.87 mg/mL) of lipopeptides biosurfactants obtained from AF_3B. The embryos exhibit normal development and high survival rates, indicating negligible toxicity. Overall, this study highlights B. velezensis strain AF_3B as a valuable candidate against bacterial and fungal diseases and foodborne pathogens, and in healthcare sector, underscoring the potential of lipopeptides biosurfactants in diverse industrial applications.
