Effects of voluntary wheel running on appetite-regulating peptides and neuroinflammation in the hypothalamus of ovariectomized middle-aged mice.
Article in Frontiers in molecular neuroscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The postmenopausal period is associated with an increased tendency to gain weight. This may be due to disturbances in appetite regulation, mainly in the hypothalamus and nutritional behaviors, as well as persistent neuroinflammation resulting from estrogen deficiency. Research indicates that physical activity may counteract estrogen deficiency by improving hypothalamic regulation of appetite and inflammation, thereby promoting better energy balance and decreasing the risk of weight gain after menopause. We investigated whether voluntary wheel running (VWR) impacts factors related to appetite, energy homeostasis, and neuroinflammatory changes induced by ovariectomy (OVX). Thus, 13-month-old female mice underwent OVX, creating a comprehensive model of reproductive aging in females. Ovariectomized (OVX-VWR) and sham-operated (SHAM-VWR) mice were subjected to 6 weeks of VWR. The control sedentary groups (SHAM-SED, OVX-SED) were housed with immobilized wheels. The body mass, food and water intake, and daily running activity were recorded. Hypothalamic and serum samples were collected to examine the expression levels of genes, proteins, and hormones related to appetite regulation and neuroinflammation processes. OVX mice gained weight most excessively and showed reduced running activity. OVX downregulated the ERα/ERβ ratio, and VWR increased ERβ expression. VWR increased Lepr and Cckar expression in the sham-operated group. VWR has an impact on hypothalamic neuroinflammation regardless of ovarian status, through changes in expression of NLRP3, pro-IL-18, TLR4, pro-caspase 1,
