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
Apoptosis is the primary pathological feature of neuronal injury caused by cerebral ischemia-reperfusion (I/R). The detailed molecular mediators are still being debated. This study aims to examine the effects of cerebral ischemia-reperfusion on apoptosis and NGF-Akt/Bad axis in rat hippocampus alone and in combination with NAC (N-Acetylcysteine). Rats were subjected to common carotid artery occlusion (CCAO) for 20 min followed by 24 h reperfusion. NAC (150 mg/kg) was given intraperitoneally (ip) one hour before ischemia and five minutes before reperfusion. TUNEL staining of hippocampus neurons revealed that the number of apoptotic neurons was elevated 24 h after reperfusion. At the molecular levels, I/R injury resulted in an increased protein expression of cleaved caspase3/procaspase3 ratio and cytochrome c level with a concomitant down-regulation of NGF, p-AKT/AKT, p-Bad/Bad and p-Trk/Trk ratio. NAC treatment significantly reduced the apoptotic damage and also reversed NGF, p-AKT/AKT, p-Bad/Bad, and p-Trk/Trk ratio in hippocampus neurons in I/R rats. In conclusion, our data showed that NGF-Akt/Bad axis may play a regulatory role in hippocampus cell death, providing a new target for a novel therapeutic strategy during transit ischemic stroke. NAC has been shown to reverse molecular alterations, suggesting its potential as an effective agent against hippocampal apoptosis following acute I/R injury.
