Morphological Features and HIF1-Dependent Processes in the Brain of Progeny of Female Rats Exposed to Maternal Hypoxia.
Article in International journal of molecular sciences, 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
Fetal hypoxia and maternal stress during pregnancy are major risk factors for neurological disorders. The effects of maternal hypoxia may be transmitted to the next generation through persistent alterations in maternal endocrine and metabolic regulation. In this study, using immunohistochemistry, quantitative RT-PCR, and Western blotting, we assessed morphological features and HIF1-dependent processes in the fetal and adult brains of progeny of female rats exposed to maternal hypoxia (PMH). We identified a delay in progenitor cell differentiation into neurons at embryonic day 14, a decreased number of neurons in the hippocampus, an increased number of astrocytes in the prefrontal cortex, and a decreased number of astrocytes in the raphe nuclei of the PMH rats. However, no significant changes were observed in HIF1α protein levels or in the protein levels of HIF1-dependent gene products in the examined brain structures. Thus, the transgenerational effect of maternal hypoxia is manifested as structural disturbances of brain development but is not accompanied by changes in HIF1-dependent metabolism.
