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
Maternal exercise during pregnancy is widely recognized as an effective means of promoting cardiovascular health in offspring. Few studies have explored how maternal exercise impacts vascular function and phenotypic switching in hypertensive offspring, despite the known involvement of vascular structural and functional remodeling in hypertension pathogenesis. Research indicates a significant relationship between elevated blood pressure and fibroblast growth factor 21 (FGF21) levels. It remains unclear whether maternal exercise during pregnancy can improve vascular function in hypertensive offspring by regulating FGF21 and its underlying mechanisms. In this study, pregnant spontaneously hypertensive rats and Wistar-Kyoto rats were randomly assigned to either a sedentary or exercise group. The exercise group underwent weightless swimming exercise from gestation day 1 (GD1) to GD20. The aim was to investigate the epigenetic modifications mediated by histone deacetylase sirtuin 1 (SIRT1) during the fetal period and the phenotypic changes in the mesenteric arteries (MAs) of hypertensive offspring. We found that maternal exercise significantly improved vascular remodeling in hypertensive offspring. Specifically, maternal exercise upregulated SIRT1 expression, which led to decreased H3K9ac (histone H3 lysine 9 acetylation) in the promoter region of the FGF21 gene. This epigenetic modification resulted in the transcriptional downregulation of FGF21 in the MAs of hypertensive fetuses. These results suggest that maternal exercise may lower blood pressure in hypertensive offspring by regulating deacetylation of the FGF21 gene promoter region through SIRT1, thereby reversing phenotypic switching and vascular structural remodeling.
