1 · What the graph read from it

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.

2 · The registry

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

backgroundThis study investigated depot-specific mRNA expression of uncoupling protein 1 (UCP1) in human white adipose tissue (WAT) and its association with obesity-related markers.

methodsWe recruited 39 normal-weight, 41 nondiabetic obese, and 22 diabetic obese women. We measured UCP1 mRNA expression in abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT), and investigated the associations between UCP1 mRNA expression in VAT and SAT, and obesity-related markers including mRNA expression of leptin, adiponectin, CCAAT-enhancer-binding protein homologous protein (CHOP), and positive regulatory domain-containing protein 16 (PRDM16). We also evaluated UCP1 mRNA expression in differentiated human white adipocytes after treatment with various stressors and metabolic improvement agents in vitro.

resultsUCP1 mRNA in VAT was significantly higher than in SAT in all groups. UCP1 mRNA in SAT was negatively correlated with BMI, total abdominal fat area, visceral fat area, blood pressure, fasting glucose, insulin, HOMA-IR score, triglyceride, hsCRP, fasting leptin levels, and adipocyte size. UCP1 mRNA in SAT was positively correlated with fasting adiponectin levels. UCP1 mRNA in VAT was negatively correlated with visceral-to-subcutaneous fat ratio (VSR), fasting glucose, and triglyceride levels. In SAT, UCP1 mRNA was negatively correlated with mRNA expression of leptin and CHOP, and positively correlated with mRNA expression of adiponectin. The expression of PRDM16 was positively correlated with UCP1 mRNA in both VAT and SAT. UCP1 mRNA expression in differentiated human white adipocytes was significantly reduced after incubation with thapsigargin, tunicamycin, homocysteine, TNF-α, or IL-β, and significantly increased after incubation with exendin 4, dapagliflozin, and telmisartan.

conclusionsThis study demonstrated depot-specific mRNA expression of UCP1 and its association with obesity-related markers in human WAT. UCP1 mRNA in human white adipocytes was suppressed by inflammatory agents and enhanced by metabolic improvement agents. UCP1 in human WAT might participate in the pathogenesis of obesity-related metabolic diseases.
