Effects of high-fat diet-induced obesity on circulating bone turnover markers in mice: a meta-analysis.
Review in Frontiers in physiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: To investigate the level of bone turnover markers in the serum of mice induced into obesity by a high-fat diet, comparing them with non-obese counterparts. Data sources: PubMed, Cochrane Library, Embase, EBSCO, and Web of Science were searched from database inception to July 22, 2026. Methods: Two researchers screened literature based on inclusion and exclusion criteria, extracting valid data for quality evaluation. meta-analysis was conducted using Review Manager 5.4 software, focusing on primary outcomes related to blood biochemical markers associated with bone metabolism, such as TRAP, CTX-1, and OCN levels. Results: Seven studies were included in the systematic review, of which five reported sufficiently comparable data for inclusion in the meta-analysis. Five articles, encompassing data from 256 mice, met the inclusion criteria. Compared to the non-obese group, the serum of obese mice exhibited a significant increase in TRAP levels (MD=1.68 U/L, 95% CI=1.08-2.27, P<0.00001) as well as CTX-1 levels (MD=9.87 ng/mL, 95% CI=5.53-14.22, P<0.00001), with no statistically significant difference in OCN levels (SMD=0.26, 95% CI=-0.78-1.30, P=0.63). Conclusion: Current evidence from a limited number of animal studies suggests that high-fat diet-induced obesity may be associated with increased circulating levels of selected bone resorption markers, including TRAP and CTX-I, in mice. No statistically significant difference was observed for OCN. Given the small number of studies, methodological limitations, substantial heterogeneity in the OCN analysis, and the absence of quantitative structural skeletal outcomes, these findings should be considered preliminary.
