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
Introduction: Obesity, driven by adipose tissue dysfunction, is a major global health challenge and a key contributor to metabolic disorders. Although taurine shows anti-obesity potential, its precise mechanisms for attenuating adipocyte lipid accumulation remain unclear. Methods: In this study, high-fat diet (HFD)-induced obese mice were treated orally with taurine (700 mg/kg/day) for 14 weeks. Systemic obesity-related parameters were evaluated, with a focus on epididymal white adipose tissue (eWAT). UPLC-MS-based metabolomics combined with multivariate analysis was employed to characterize metabolic alterations in eWAT. Additionally, 3T3-L1 adipocyte spheroids were treated with taurine (0-0.5 mM), either alone or in combination with the cannabinoid receptor type 1 (CB1) agonist CP55940 or antagonist AM6545, to assess its effects on lipid accumulation and underlying mechanisms. Results: Focusing on adipose tissue, taurine treatment effectively countered HFD-induced metabolic disturbances, particularly by suppressing epididymal fat mass accumulation and ameliorating adipocyte hypertrophy. Metabolomic profiling of eWAT revealed that taurine treatment reversed 15 out of 35 metabolic alterations, including the reduction of three anandamide (AEA) precursors, implying that taurine may alter endocannabinoid (eCB) biosynthesis by limiting precursor availability. Moreover, taurine suppressed lipid accumulation by inhibiting CB1 signaling, a mechanism supported by downregulation of lipogenic genes (including Conclusion: Collectively, our findings demonstrate that taurine exerts its anti-obesity effects partially via modulation of eCB-CB1 signaling, coordinately inhibiting lipogenesis and promoting lipolysis, thereby highlighting its therapeutic potential for obesity management.
