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 aim of present work was to elucidate the role of actin-depolymerizing factor (ADF), an important regulator of actin cytoskeleton, in the oxidized low-density lipoprotein (ox-LDL)-induced blood-brain barrier (BBB) disruption. The primary mouse brain microvascular endothelial cells (MBMECs) were exposed to ox-LDL. Treatment with LDL served as control. It was found that ADF mRNA level and protein expression were decreased when exposed to ox-LDL in MBMECs. Then, we investigated the influence of ADF overexpression on ox-LDL-treated MBMECs. Structurally, overexpression of ADF inhibited ox-LDL-induced F-actin formation. Functionally, overexpression of ADF attenuated ox-LDL-induced disruption of endothelial barrier marked by restoration of transendothelial electrical resistance, permeability of Evans Blue and expression of tight junction-associated proteins including ZO-1 and occludin, and blocked ox-LDL-induced oxidative stress marked by inhibition of reactive oxygen species (ROS) formation and activity of NADPH oxidase and Nox2 expression. However, overexpression of ADF in control cells had no significant effect on endothelial permeability and ROS formation. In conclusion, overexpression of ADF blocks ox-LDL-induced disruption of endothelial barrier. In addition, siRNA-mediated downregulation of ADF expression aggravated ox-LDL-induced disruption of endothelial barrier and ROS formation. These findings identify ADF as a key signaling molecule in the regulation of BBB integrity and suggest that ADF might be used as a target to modulate diseases accompanied by ox-LDL-induced BBB compromise.
