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
Increasing evidence suggests that Ras-related in brain 7 (Rab7), an endosome-localized small GTPase contributes to cerebral ischemic brain injury. In the present study, we investigated the role of Rab7 in ischemic stroke-induced formation of astrogliosis and glial scar. Rats were subjected to transient middle cerebral artery occlusion (tMCAO); the rats were injected with the Rab7 receptor antagonist CID1067700 (CID). Primary astrocytes were subjected to an oxygen and glucose deprivation and reoxygenation (OGD/Re) procedure; CID was added to the cell culture media. We found that Rab7 was significantly elevated over time in both the in vivo and in vitro astrocytic injury models, and administration of CID significantly down-regulated the glial scar markers such as glial fibillary acidic protein (GFAP), neurocan and phosphacan. Moreover, administration of CID significantly attenuated the brain atrophy and improved neurologic deficits in tMCAO rats, and protected astrocytes against OGD/Re-induced injury. Further, CID downregulated the protein levels of Lamp1 and active cathepsin B in astrocytes after OGD/Re or tMCAO injury; CID inhibited the co-localization of cathepsin B and Rab7, Lamp1 and Rab7; CID decreased OGD/Re-induced increase in lysosomal membrane permeability and blocked OGD/Re-induced release of cathepsin B from the lysosome into the cytoplasm in astrocytes. Taken together, these results suggest that Rab7 is involved in ischemic stroke-induced formation of astrogliosis and glial scar. CID administration attenuates brain atrophy and improves neurologic deficits and inhibits astrogliosis and glial scar formation after ischemic stroke via reducing the activation and release of cathepsin B from the lysosome into the cytoplasm.
