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
backgroundSevere renal ischemia-reperfusion injury results in worse outcomes of kidney transplantation. Compared to the collecting duct, the proximal tubule is more likely to exhibit severe pyroptosis and damage during renal ischemia-reperfusion. Aquaporins were reported of having regulatory roles in pyroptosis. We explored whether aquaporin 2 overexpression in proximal tubular cells could alleviate ischemia-reperfusion injury related pyroptosis.
methodsA renal ischemia-reperfusion model of mice was established, and human kidney 2 cells were treated with hypoxia-reoxygenation. Aquaporin 2 overexpression was achieved in human kidney 2 cells transfected with lentivirus, which were then cultured with murine cells. Renal tissues and serum of the mice, and human kidney 2 cells were subjected to histological, molecular, and biochemical examinations.
resultsCompared with the sham group, the renal function of the ischemia-reperfusion group was significantly decreased, and the tissue injury was severe and accompanied by more nuclear dissolved and necrosis. Besides, the expression of aquaporin 1-5 decreased significantly, while the expression of Toll-like receptor 4, caspase-1, kim-1 and interleukin 1β and 18 increased significantly in ischemia-reperfusion group. Similar results were observed in the human kidney 2 cells test. Overexpression of aquaporin 2 partially reversed the cell damage, pyroptosis, and molecular expression changes of human kidney 2 cells induced by hypoxia-reoxygenation.
conclusionsOur findings suggest that aquaporin 2 overexpression can potentially reduce pyroptosis in proximal tubular cells, and thus might be a novel target for relieving pyroptosis and injury in renal ischemia-reperfusion injury.
