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 endothelial cells (VECs) dysfunction has been revealed to be a major cause of various cardiovascular diseases. Yet, the precise cellular and molecular mechanisms of VECs injury remain elusive. This study aims to investigate the roles and molecular mechanisms of RNA binding protein IGF2BP3 in vascular endothelial cell injury caused by oxidized low-density lipoprotein (ox-LDL). HUVECs were treated with ox-LDL to induce endothelial cell injury, and the cellular responses to ox-LDL were assessed using cell viability and apoptosis assays. IGF2BP3 was expressed at low levels in vascular tissues from atherosclerosis patients. Treatment with ox-LDL significantly decreased the expression of IGF2BP3 in HUVECs. Overexpression of IGF2BP3 effectively reduced the injury induced by ox-LDL. Glucose metabolism enzymes were significantly downregulated in vascular tissues from atherosclerosis patients and in HUVECs treated with ox-LDL, leading to suppressed glucose metabolism. IGF2BP3 upregulated the glucose metabolism enzyme LDHA to alleviate the injury caused by ox-LDL in HUVECs. Analysis of the LDHA sequence revealed the presence of an IGF2BP3 binding motif in its 3'UTR. Further experiments including RNA pull-down, RNA IP, and RNA stability assays confirmed the specific binding of IGF2BP3 to the 3'UTR region of LDHA, stabilizing its transcripts. Rescue experiments demonstrated that IGF2BP3 mitigated vascular endothelial cell injury by regulating LDHA-mediated glucose metabolism. The outcomes of this study elucidate the protective roles of IGF2BP3 in safeguarding vascular endothelial cells against injury.
