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

aims/hypothesisRecently, FTO was identified as a candidate gene contributing to both childhood and severe adult obesity. We tested the hypothesis that mRNA expression of FTO and/or of the neighbouring RPGRIP1L in adipose tissue correlates with measures of obesity and fat distribution. We also investigated whether the FTO obesity risk alleles might explain variability in FTO and RPGRIP1L mRNA expression.

methodsIn paired samples of visceral and subcutaneous adipose tissue from 55 lean and obese participants, we investigated whether FTO and RPGRIP1L mRNA expression is fat depot-specific, altered in obesity and related to measures of fat accumulation, insulin sensitivity and glucose metabolism. All participants were genotyped for the obesity-associated rs8050136 FTO variant.

resultsFTO mRNA expression was threefold higher in subcutaneous than in visceral adipose tissue. Subcutaneous FTO expression correlated with visceral FTO expression. FTO gene expression in both depots correlated with age and was negatively correlated to BMI and per cent body fat. FTO mRNA levels were not related to measures of insulin sensitivity and glucose metabolism. RPGRIP1L mRNA expression was 1.6-fold higher in visceral than in subcutaneous adipose tissue, but did not correlate with anthropometric and metabolic characteristics. There was no association between rs8050136 and FTO or RPGRIP1L mRNA expression in adipose tissue. CONCLUSIONS/

interpretationExpression of adipose tissue FTO mRNA is fat depot-specific and negatively correlates with measures of obesity. However, the direction of this relationship still needs to be elucidated.
