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 role of cell-specific ANGPTL4 is not well known in the context of ECs, specifically in pathological angiogenesis and its relation to diabetic kidney disease. Here, we demonstrate that endothelial ANGPTL4 is required to induce a metabolic phenotype that favors mesenchymal activation in ECs and tubules in diabetic conditions. Diabetes accelerates mesenchymal activation and fibrogenesis in control mice however, the same effects were not observed in endothelial-cell specific knock out mice. This mesenchymal activation in diabetes is directly linked with pathological neovascularization, endothelial leakage, lipid and glycolysis metabolite load, de novo lipogenesis (DNL) and related mitochondrial damage, activation of the immune system, c-GAS-STING activation and transcription of pro-inflammatory cytokines. However, endothelial ANGPTL4-depleted mice had stable vessels, improved levels of lipid and glucose metabolism, suppressed levels of DNL, restored mitochondrial function, and mitigated levels of c-GAS-STING-mediated inflammation. Moreover, Inhibition of DNL, and STING via small molecule inhibitors suppressed pathological neovascularization and endothelial leakage, normalized fatty acid oxidation and reduced pathological glycolysis and de novo lipogenesis (DNL). These data demonstrate the crucial roles of endothelial ANGPTL4 in regulating pathogenic angiogenesis in the renal vasculature during diabetes.
