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
backgroundProbiotics, defined as live microorganisms that confer a health benefit on the host when administered in adequate amounts, often require protective strategies to ensure their viability in food products. Immobilization in biopolymeric matrices presents a promising approach for enhancing bacterial resilience. This study focused on the fabrication of bacterial cellulose films as a platform for immobilizing Lactobacillus acidophilus. The physicochemical properties of the immobilized probiotic were investigated using Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and thermogravimetric analysis (TGA). The release profile and viability of the bacteria were also evaluated under simulated gastrointestinal environments (simulated gastric fluid and simulated intestinal fluid).
resultsThe FTIR spectra confirmed the presence of the probiotic bacteria in the cellulose film. The FE-SEM results showed that the probiotic film had a smooth structure with reduced pores. XRD analysis also revealed that immobilizing probiotics in the cellulose film changes its crystalline structure to an amorphous state. TGA demonstrated the composite film's thermal stability, with mass losses of approximately 20% and 70.33% at 200 and 600 °C, respectively. The in vitro release profile demonstrated that immobilization significantly improved bacterial survival in simulated environments, particularly in simulated intestinal fluid.
conclusionCollectively, these results indicate that the probiotic L. acidophilus was qualitatively incorporated in the cellulose film, and its survival rate was maintained during storage time. This suggests potential as an efficient carrier in the functional food and pharmaceutical industries. © 2026 Society of Chemical Industry.
