Compensatory effects of serotonin on the regulation of blood volume in healthy human subjects.
Article in Physiological reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
It has been demonstrated that water intake accelerates the release of serotonin from enterochromaffin cells in the rat jejunum, which is then transported through the portal vein into the blood. However, the physiological roles of serotonin in the regulation of blood volume remain unclear. We aimed to investigate the roles of serotonin in the physiological regulation of physical exercise-dependent sweating-mediated haemoconcentration in humans. All participants performed two times 30-min sessions of -up-and-down physical exercise with a 20-min rest. Changes in thermal perspiration rate, concentrations of serotonin and vasopressin in blood, and samples of blood and urine were measured just before and after repeated exercise. All participants presented increased vasopressin after the first trial but showed no change after the second exercise session. In contrast, blood serotonin levels increased dramatically after the second session. Urine osmolality increased significantly after the first exercise session. All the participants showed significantly decreased ratios of red blood cells, hemoglobin, and neutrophils before and after the second exercise. In contrast, no significant changes were observed in the ratios of total protein and lymphocytes. In conclusion, serotonin may play a crucial role in the compensatory regulation of sweating-mediated haemoconcentration in cooperation with vasopressin.
