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 current study investigated the physiological mechanisms by which extracellular vesicle (EV)-encapsulated miR-181a-2-3p derived from mesenchymal stem cells (MSCs) might mediate oxidative stress (OS) in Parkinson's disease (PD). First, 6-hydroxydopamine (6-OHDA)-induced PD cell and mouse models were established, after which miR-181a-2-3p, EGR1, and NOX4 expression patterns were determined in SH-SY5Y cells and substantia nigra (SN) of PD mice. Next, the binding affinity among miR-181a-2-3p, EGR1, and NOX4 was identified using multiple assays. Gain- or loss-of-function experiments were further adopted to detect SH-SY5Y cell proliferation and apoptosis and to measure the levels of SOD, MDA, and ROS. Finally, the effects of miR-181a-2-3p from MSC-derived EVs in PD mouse models were also explored. It was found that miR-181a-2-3p was poorly expressed in 6-OHDA-induced SH-SY5Y cells, whereas miR-181a-2-3p from MSCs could be transferred into SH-SY5Y cells via EVs. In addition, miR-181a-2-3p could target and inhibit EGR1, which promoted the expression of NOX4. The aforementioned miR-181a-2-3p shuttled by MSC-derived EVs facilitated SH-SY5Y proliferation and SOD levels, but suppressed apoptosis and MDA and ROS levels by regulating EGR1 via inhibition of NOX4/p38 MAPK, so as to repress OS of PD. Furthermore, in PD mice, miR-181a-2-3p was carried by EVs from MSCs to alleviate apoptosis of dopamine neurons and OS, accompanied by increased expressions of α-syn and decreased 4-HNE in SN tissues. Collectively, our findings revealed that MSC-derived EV-loaded miR-181a-2-3p downregulated EGR1 to inhibit OS via the NOX4/p38 MAPK axis in PD.
