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
Diabetic retinopathy (DR) ranks among the primary causes of adult blindness globally. Oxidative stress and mitochondrial dysfunction play a critical role in the progression of DR. Mounting data indicated that small extracellular vesicles (sEVs) of mesenchymal stem cell (MSC) have the ability to transport bioactive chemicals to target cells, leading to changes in their phenotype. Nevertheless, it remains elusive how MSC-derived sEVs regulate oxidative stress and mitochondrial function in DR. MSC-sEVs was intravitreally injected to streptozotocin (STZ)-treated Sprague-Dawley rats to assess the therapeutic effects on DR. The underlying regulatory mechanism was investigated by coculturing advanced glycation end-products (AGEs)-induced rat Müller cells with/without PTP1B overexpression with MSC-sEVs in vitro, with or without miR-125a-5p suppression. Intravitreal injection of MSC-sEVs improved histological morphology and blood-retinal barrier function, alleviated Müller gliosis, decreased PTP1B expression, redox stress and apoptosis in retina of diabetic rat. MSC-sEVs decreased the accumulation of ROS and improved the structure and function of mitochondria of Müller cells with AGEs treatment. Mechanically, MSC-sEVs activated the mitophagy of AGEs-treated Müller cells, represented by an increased expression of the LC3II/LC3I ratio, TOM20, PINK1 and Parkin along with a decreased expression of P62. Importantly, miR-125a-5p inhibitor abolished the protective effects of MSC-sEVs. Furthermore, the overexpression of PTP1B in Müller cells reduced the effects of MSC-sEVs. These findings suggested that miR-125a-5p of MSC-sEVs alleviates Müller cells injury in DR by modulating PINK1/Parkin-mediated mitophagy via PTP1B pathway.
