Interplay between volemic balance and the intestinal tract: insights on biomarkers and diagnostic tests used to assess intestinal morphofunctional barrier.
Review in Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas, 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
Volemic control is essential for maintaining tissue perfusion and fluid homeostasis, with cardiorenal and endothelial mediators regulating intravascular composition, often impaired in pathological states. Notably, intestinal epithelial cells are highly sensitive to volume fluctuations, resulting in changes in intestinal permeability that may not be detected by current diagnostic methods. This review offers a comprehensive description of the main mediators involved in volemic regulation, their impact on intestinal morphofunctionality, and specific details regarding epithelial cells. Additionally, key biomarkers - especially lactulose/mannitol - for assessing intestinal barrier disruption are highlighted, and a novel approach is proposed using liquid chromatography-mass spectrometry to investigate gut alterations in heart failure and exercise-induced stress, which are silent and neglected conditions with significant repercussions on intestinal barrier function.
