Asymmetric dimethylguanidino valeric acid as an independently associated risk factor for early hypertriglyceridemia and dyslipidemia.

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
introductionHypertriglyceridemia (HTG) is a crucial risk factor for cardiovascular disease, metabolic syndrome, and type 2 diabetes. However, its early detection remains challenging due to the dynamic fluctuations in plasma triglyceride levels and their limited utility in predicting long-term dyslipidemia.
objectivesThis study aimed to elucidate the role of asymmetric dimethylguanidino valeric acid (ADGV) in HTG through integrated cohort analyses and mechanistic cellular experiments.
methodsCirculating ADGV levels were quantified in a cross-sectional cohort from southern China (n = 588) and assessed its prospective association with incident HTG in an independent prospective cohort from northern China (n = 348, median follow-up: 1.8 years). Hepatocyte experiments were performed to examine biological plausibility and explore potential mechanisms linking ADGV to hepatic triglyceride metabolism.
resultsElevated ADGV levels were significantly associated with increased risk of HTG and remained independently associated after adjustment for age, gender, BMI, eGFR, lifestyle factors, and liver function. Complementary in vitro studies in hepatocytes revealed that ADGV promoted triglyceride accumulation by stimulating de novo fatty acid synthesis, mediated through regulating the expression of key metabolic genes (ACC, CPT1α, and PGC1α).
conclusionHigher circulating ADGV was independently associated with prevalent and incident hypertriglyceridemia across a cross-sectional cohort and an independent prospective cohort, and hepatocyte experiments support a contributory role of ADGV in hepatic lipogenesis.
