Long-term body mass index trajectories and dyslipidemia and related gut microbial features: results from the China health and nutrition survey 1991-2018.
Article in BMC public health, 2025. 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
objectiveTo discover the associations between long-term body mass index (BMI) trajectories and dyslipidemia, and the internal mechanism within different BMI trajectory populations.
methodsWe chose 11,499 adults from China Health and Nutrition Survey (CHNS) for trajectory modeling. Selected those with two blood lipid measurements (n = 2,003), and determine the risk trajectory group associated with dyslipidemia. We selected two subsets of the 2015 CHNS, CHNS-1 (n = 3,061) and CHNS-2 (n = 1,409) for gut microbiome analysis. A Lasso regression in both the CHNS-1 and the CHNS-2 confirmed the dominant genera of each dyslipidemia risk trajectory. We also used a subset of CHNS-2 (n = 779) with metabolomics data to identify the differential metabolites. We ascertained the connection between microbiome and metabolites via correlation analysis.
resultsWe identified three BMI trajectories: The developing into overweight (DO) group and the overweight to obesity (OTO) group had increased dyslipidemia risks compared to the normal stable (NS) group, OR: 1.69(95%CI: 1.30,2.20);1.93(95%,CI:1.34,2.77). There are significant differences in gut microbiota between OTO/DO group and NS group, PERMANOVA R
conclusionsA high-level BMI change trajectory will increase the risk of developing dyslipidemia in the future. The growth trajectory of BMI affects lipid metabolism mediated by gut microbiota.These findings may reveal the mechanism of BMI changes leading to dyslipidemia, and indicate the corresponding microbiome targets for prevention.
