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
BACKGROUND The beneficial effect of Δ-17 FAD is poorly understood. The aim of this study was to investigate the protective mechanism of fatty acids against atherosclerotic (AS) damage induced by oxidized low-density lipoprotein (ox-LDL) in human umbilical vein endothelial cells (HUVECs), and to identify the molecular mechanisms involved. MATERIAL AND METHODS The ox-LDL was used to induce lipotoxicity in HUVECs to establish a model of oxidative injury. HUVECs were transfected with Δ-17FAD lentivirus to induce cytoprotective effects. We evaluated the alterations in cell proliferation and apoptosis, and oxidative stress index, including levels of nitric oxide (NO), malonyldialdehyde (MDA), SOD enzyme, LDH, GSH-PX, and vascular endothelial growth factor (VEGF) expression. RESULTS The ox-LDL-induced excessive cellular apoptosis of HUVECs was abrogated by upregulation of Δ-17 FAD. Importantly, Δ-17 FAD converted ω-3 polyunsaturated fatty acid ARA into ω-6 polyunsaturated fatty acid EPA. Further, Δ-17 FAD overexpression promoted the proliferation of HUVECS, and inhibited ox-LDL-induced lipid peroxidation of HUVECs. The levels of nitric oxide, GSH-PX, and SOD enzyme were increased, and the activity of MDA and LDH was suppressed by the upregulation of Δ-17 FAD. In addition, upregulation of Δ-17 FAD significantly increased VEGF expression. In vitro tube formation assay showed that Δ-17 FAD significantly promoted angiogenesis. CONCLUSIONS These results suggest that Δ-17 fatty acid desaturase plays a beneficial role in the prevention of ox-LDL-induced cellular damage.
