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
Vascular smooth muscle cell (VSMC) phenotypic switching is a hallmark of vascular remodeling that contributes to atherosclerotic diseases. MicroRNA 4463 (miR-4463) has been implicated in the development of arteriosclerosis obliterans, whereas the underlying mechanisms in VSMCs have not been fully addressed. In this study, we assessed whether miR-4463 is involved in the phenotypic switching process in VSMCs. Oxidized low-density lipoprotein (Ox-LDL, 50 mg/L) was used to simulate the oxidative stress condition, and miR-4463 expression in VSMCs was detected by a quantitative polymerase chain reaction. To determine the effect of Ox-LDL-mediated regulation of miR-4463 on the phenotypic switching of VSMCs, cell counting kit-8, cell migration assays, and cytoskeleton test were performed. After using specific antagonists of c-Jun N-terminal kinase (JNK) and extracellular signal-regulated kinase (ERK), the relationship between miR-4463 and its downstream signaling proteins was explored. Ox-LDL induced oxidative stress to promote VSMC transformation from contraction to secretion, which clearly decreased the level of miR-4463. Then, downregulated miR-4463 enhanced the migration and phenotypic transformation of VSMCs and activated the phosphorylation of JNK and ERK; these effects were increased after Ox-LDL induction. As expected, inhibiting the two signaling proteins blocked the effect of the miR-4463 inhibitor combined with Ox-LDL. In addition, inhibition of miR-4463 led to the upregulation of basic fibroblast growth factor (bFGF) expression. The results of this study demonstrate that miR-4463 is a novel regulator of VSMC function in hypoxic conditions and modulates VSMC phenotypic switching via the JNK and ERK signaling pathways; bFGF may be the target gene of miR-4463.
