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
Abnormal proliferation and migration of endothelial cells are key contributors to tumor angiogenesis. Recent studies have shown that the crucial role of E3 ubiquitin ligase neuronal precursor cell expression developmentally downregulated 4-like (NEDD4L) in tumorigenesis. However, the precise mechanisms by which NEDD4L functions in endothelial cells remain unclear. In this study, we investigate the mechanisms by which NEDD4L influences the function of human umbilical vein endothelial cells (HUVECs) and its effect on tumor angiogenesis. Our results show that NEDD4L overexpression in HUVECs suppresses both cell proliferation and migration. Additionally, we find that the autophagic activity in NEDD4L-overexpressing cells is increased. Proteomic profiling and ubiquitination assays reveal that NEDD4L interacts with eEF1A1, promoting K48-linked ubiquitination-mediated degradation of eEF1A1. This post-translational modification is a key step in the NEDD4L-mediated regulation of autophagy and cellular function. Moreover, we find that loss of endothelial NEDD4L significantly enhances tumor growth and promotes angiogenesis
