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
3-benzyl-5-((2-nitrophenoxy) methyl)-dihydrofuran-2(3 H)-one (3BDO) is a mTOR agonist that inhibits autophagy. The main purpose of this study is to investigate the effects of 3BDO on seizure and cognitive function by autophagy regulation in pentylenetetrazol (PTZ)-kindled epileptic mice model. The PTZ-kindled epileptic mice model was used in study. The behavioral changes and electroencephalogram (EEG) of the mice in each group were observed. The cognitive functions were tested by Morris water maze test. The loss of hippocampal neurons was detected by hematoxylin-eosin (HE) staining and immunofluorescence analysis. Immunohistochemistry, western blot and q-PCR were employed to detect the expression of autophagy-related proteins and mTOR in the hippocampus and cortex. Less seizures, increased hippocampal neurons and reduced astrocytes of hippocampus were observed in the 3BDO-treated epileptic mice than in the PTZ-kindled epileptic mice. Morris water maze test results showed that 3BDO significantly improved the cognitive function of the PTZ-kindled epileptic mice. Western blot analyses and q-PCR revealed that 3BDO inhibited the expression of LC3, Beclin-1, Atg5, Atg7 and p-ULK1/ULK1, but increased that of p-mTOR/mTOR, p-P70S6K/P70S6K in the hippocampus and temporal lobe cortex of epileptic mice. Immunohistochemistry and immunofluorescence also showed 3BDO inhibited the LC3 expression and increased the mTOR expression in the hippocampus of epileptic mice. In addition, the autophagy activator EN6 reversed the decrease in the 3BDO-induced autophagy and aggravated the seizures and cognitive dysfunction in the epileptic mice. 3BDO regulates autophagy by activating the mTOR signaling pathway in PTZ-kindled epileptic mice model, thereby alleviating hippocampus neuronal loss and astrocytes proliferation, reducing seizures and effectively improving cognitive function. Therefore, 3BDO may have potential value in the treatment of epilepsy.
