The Role of Nrf2 on the Cognitive Dysfunction of High-fat Diet Mice Following Lead Exposure.
Article in Biological trace element research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 6 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
Lead (Pb) exposure can induce the severe deleterious damage on the central nervous system (CNS). High-fat diet also has been suggested that it had some adverse effects on learning and memory, cognitive function, but there is lack of study on Pb and high-fat diet co-exposure on the CNS damage. In this study, the goal was to explore the effect of Pb on the cognitive function of mice with high-fat diet and to investigate whether Nrf2 signaling pathway acts in the cerebral cortex. C57BL/6J mice were randomly divided into control, high-fat diet, Pb (drinking water with 250 mg/L lead acetate), and high-fat diet with Pb (drinking water with 250 mg/L lead acetate) co-exposure groups for 12 weeks. Experiment data showed that learn memory and exploration ability of mice obviously decreased in Pb and high-fat diet, and reactive oxygen species (ROS) increased; then, the protein expressions of Nrf2, heme oxygenase-1, NADP(H):dehydrogenase quinone 1, and superoxide dismutase 2 were lower significantly compared with those in the control group. This study suggested that down-expressed Nrf2 signaling pathway possibly related to the cognitive dysfunction induced by Pb and high-fat diet co-exposure.
