Cytoprotective Effects of Lactic Acid Bacteria and Yeast Cell-Free Supernatants Against Acrylamide-Induced Damage in Caco-2 Cells.
Article in Probiotics and antimicrobial proteins, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acrylamide (AA) is a food-derived contaminant linked to oxidative stress and genotoxicity in intestinal epithelial cells. This study had two objectives: (i) to evaluate the protective effects of cell-free supernatants from Lacticaseibacillus rhamnosus 0997 and Kluyveromyces lactis 0028 against AA-induced damage in Caco-2 cells, and (ii) to investigate AA-induced changes in the surface and functional properties of selected lactic acid bacteria and yeast strains. Cell-free supernatants significantly enhanced DNA repair, reduced genotoxicity, and decreased intracellular reactive oxygen species in Caco-2 cells in a concentration- and AA-dose-dependent manner (p < 0.05). L. rhamnosus 0997 showed stronger cytoprotection at higher AA concentrations, whereas K. lactis 0028 was more effective under lower AA exposure. Independently, AA altered auto-aggregation, biofilm formation, hydrophobicity, adhesion, and zeta potential of the tested microbial strains in a strain-specific manner. These findings demonstrate the cytoprotective potential of microbial cell-free supernatants against AA-induced cellular damage and characterize the effects of AA on selected microbial surface properties.
