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
backgroundObesity is an important risk factor for cardiometabolic disease, including dyslipidemia and atherosclerotic cardiovascular disease. Although the role of the liver in dyslipidemia is established, the contribution of adipose tissue is less clear. This study aims to clarify the role of adipose tissue in lipid metabolism and dyslipidemia.
methodsWe conducted a cross-sectional analysis of 125 patients from the BARIA (The Immune System and Microbial Tone in Relation to NAFLD/NASH Before and After Bariatric Surgery in the Morbidly Obese in Amsterdam) longitudinal cohort study undergoing bariatric surgery. Comprehensive phenotyping included fasting untargeted plasma metabolomics, lipid, lipoprotein, adipokine profiling, RNA sequencing, and fecal shotgun metagenomics. Tissue transcriptomic and plasma metabolites were compared between individuals with and without dyslipidemia.
resultsDyslipidemia was present in 43 of 125 individuals (34.4%), with higher triglycerides (1.62 versus 1.24 mmol/L), apoB (apolipoprotein B; 93.15 versus 81.81 mg/dL), and lower high-density lipoprotein (1.02 versus 1.35 mmol/L) and apoAI (136.40 versus 161.35 mg/dL). Plasma adipokines showed limited differences: leptin concentrations were lower in dyslipidemia in unadjusted analysis but reduced after adjustment for age, sex, and body weight (adjusted
conclusionsDyslipidemia in obesity is associated with transcriptomic alterations in adipose tissue, including subcutaneous adipose tissue, involving inflammation, oxidative stress, and adipogenesis. These findings support a role of adipose tissue in lipid regulation beyond hepatic pathways.
