Comparable organs weights and histopathological changes after administration of dexamethasone during pregnancy in rats.
Article in Open veterinary journal, 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
Background: Dexamethasone, a synthetic analogue of betamethasone, exerts vast actions to mediate anti-inflammatory and immunosuppressive effects. Despite failing to exhibit obvious adverse involvements during its protective therapy, the unique role of dexamethasone affects an array of organs implicated in preliminary histopathological findings. Aim: This prospective study aimed to verify the alterations in the liver, brain, kidney, and spleen of pregnant rats treated with low-versus high-dexamethasone doses. Methods: Overall, 72 Wistar rats weighing 250 ± 20 g were divided into the control pregnant group, which was subdivided into two subgroups (14 and 21 days); the pregnant group, which was ultimately subdivided into two groups and then orally administered diluted concentrations of dexamethasone at 625 and 125 × 10 Results: Histological sections from the liver, brain, kidney, and spleen were further stained with hematoxylin and eosin and then examined under a microscope to evaluate tissue integrity and histopathological lesions. Dexamethasone exhibited significant adverse effects on total organ weights. Significant histopathological variations in dexamethasone-treated tissues. Therefore, liver changes included hepatocyte necrosis and interstitial inflammation. Structural brain changes involving neuronal necrosis and perineuronal vacuolations. Despite kidney lesions, which included dilated tubules and necrosis with sloughing of the renal epithelium, the spleen exhibited lymphoid follicle depletion and hemorrhage of red pulp. Strong, unlimited alterations (+++) of the tissues were observed in the group that received 125 × 10 Conclusion: These findings suggest that the harmful effects of dexamethasone on organ architecture are dose-dependent. Therefore, dexamethasone is not decidedly contraindicated during pregnancy, but strict consideration and incessant monitoring are required during application, irrespective of the healthcare supplier.
