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
The excessive and ectopic pulmonary artery smooth muscle cells (PASMCs) are crucial to the pathogenesis of pulmonary arteriole (PA) remodeling in pulmonary arterial hypertension (PAH). We previously found that microRNA (miR)-30a was significantly increased in acute myocardial infarction (AMI) patients and animals, as well as in cultured cardiomyocytes after hypoxia, suggesting that it might be strongly associated with hypoxia-related diseases. Here, we investigated the role of miR-30a in the PASMC remodeling of PAH. The expression of miR-30a was higher in the serum of PAH patients compared with healthy controls. miR-30a was mainly expressed in PAs and was increased in PASMCs after hypoxia, mediating the downregulation of p53 tumor suppressor protein (P53). Genetic knockout of miR-30a effectively decreased right ventricular (RV) systolic pressure (RVSP), PA, and RV remodeling in the Su5416/hypoxia-induced and monocrotaline (MCT)-induced PAH animals. Additionally, pharmacological inhibition of miR-30a via intratracheal liquid instillation (IT-L) delivery strategy showed high efficiency, which downregulated miR-30a to mitigate disease phenotype in the Su5416/hypoxia-induced PAH animals, and these beneficial effects could be partially reduced by simultaneous P53 inhibition. We demonstrate that inhibition of miR-30a could ameliorate experimental PAH through the miR-30a/P53 signaling pathway, and the IT-L delivery strategy shows good therapeutic outcomes, providing a novel and promising approach for the treatment of PAH.
