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
Acute ischemic stroke is a challenging disease that threatens the life of older people. Dysfunction of brain endothelial cells is reported to be involved in the pathogenesis of acute ischemic stroke. Ramelteon is a novel agonist of melatonin receptor developed for the treatment of insomnia. Recently, the promising protective effect of Ramelteon on brain injury has been widely reported. The present study aims to investigate the protective effect of Ramelteon against free fatty acid (FFA)-induced damages in brain vascular endothelial cells and the underlying mechanism. Firstly, we discovered that Ramelteon administration remarkably reversed the decreased cell viability, increased LDH release, activated oxidative stress, and excessive released inflammatory factors caused by FFAs. Secondly, Ramelteon extensively suppressed the attachment of U937 monocytes to bEnd.3 brain endothelial cells induced by FFAs. In addition, the elevated expression of E-selectin and the reduced expression of KLF2 induced by FFAs were pronouncedly alleviated by Ramelteon. Lastly, silencing of KLF2 abolished the protective effects of Ramelteon against FFA-induced expression of E-selectin and the attachment of U937 monocytes to bEnd.3 brain endothelial cells. In conclusion, Ramelteon mitigated FFA-induced attachment of monocytes to brain vascular endothelial cells by increasing the expression of KLF2 and reducing the expression of E-selectin.
