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

scopeTo determine whether doses of quercetin in the range of serum concentrations exert any effect on triacylglycerol accumulation in maturing preadipocytes and mature adipocytes. The influence on the expression of adipogenic markers as well as on gene expression and activity of enzymes involved in triacylglycerol metabolism were assessed. METHODS AND

results3T3-L1 preadipocytes were treated during differentiation and mature adipocytes for 24 hours with low doses (0.1-10 µM) of quercetin. Triacylglycerol content in both cell types and free fatty acid and glycerol in the incubation medium of mature adipocytes were measured spectrophotometrically. Gene and protein expression were assessed by RT-PCR and Western blot. LPL and FAS activities were quantified. During differentiation quercetin reduced triacylglycerol content at doses from 0.5 to 10 µM. 1 µM of quercetin reduced C/EBPβ gene expression, SREBP1 mature protein levels, and PPARγ gene expression. 10 µM of quercetin reduced LPL gene expression and PPARγ and SREBP1c expression. In mature adipocytes, only 10 µM of quercetin reduced triacylglycerol content. Lipogenic FAS expression and activity were reduced at this dose.

conclusionQuercetin, in the range of serum concentrations, is able to inhibit adipogenesis, but higher doses, at least 10 µM, are needed to reduce fat accumulation in mature adipocytes.
