Effects of chronic kidney disease on cognitive function and α-klotho expression in hippocampus.
Article in Translational andrology and urology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Alpha-klotho (α-KL) is not only related to the regulation of calcium-phosphorus metabolism, and fibrosis in chronic kidney disease (CKD), it is also involved in the regulation of many cognitive disorders. We conducted this study to investigate the effects of CKD on cognitive dysfunction and α-KL. Methods: Doxorubicin was used to induce a CKD model, which was validated by weight, 24-hour urine protein quantification, serum creatinine (Cr), blood urea nitrogen (BUN), and kidney hematoxylin-eosin (HE) staining. The Morris water maze (MWM) paradigm was used to assess the effects of CKD on cognitive behavior. The expression of α-KL in the hippocampus was detected using real-time quantitative polymerase chain reaction, Western blot, and immunohistochemistry (IHC). Results: (I) In the CKD group, the weight of the rats increased slowly (P<0.001), 24-hour urine protein increased (P<0.05), and Cr (P=0.026) and BUN levels (P=0.003) increased; (II) HE staining showed that in the CKD group there were changes in the structure, fibrosis, and inflammatory infiltration of the renal tissues, and changes in the structure, cell necrosis, and neuronal degeneration of the hippocampus; (III) in the MWM experiment, the escape latency of the CKD group was prolonged compared to that of the control group (P=0.043, 0.023), and the number of crossing the platform was reduced (P=0.003); (IV) in the CKD group, the expressions of α-KL messenger ribonucleic acid (P=0.0005) and α-KL protein (P=0.0005) in the hippocampus were downregulated. The IHC results showed that the expression of α-KL protein in the hippocampal region III cornus ammonis (CA3) of the CKD group region was also downregulated, and the α-KL-positive cells (P=0.019) and mean optical density (P=0.015) were decreased. Conclusions: The expression of α-KL appears to effect the cognitive function of CKD rats; thus, it may be a valuable target in the treatment of CKD with cognitive impairment.
