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

objectiveAutotaxin (ATX) is an adipocyte-derived lysophospholipase D that generates the lipid signaling molecule lysophosphatidic acid (LPA). The ATX/LPA pathway in adipose tissue has recently been implicated in obesity and insulin resistance in animal models, but the role of circulating ATX in humans remains unclear. The aim of the present study was to determine the relationship between serum ATX and insulin resistance.

methodsOlder (60-75 years), nondiabetic human participants with overweight or obesity (BMI 25-37 kg m(-2) ) were characterized for metabolic phenotype including measures of energy, glucose, and lipid homeostasis. The relationship between serum ATX and metabolic parameters was then determined using correlative and predictive statistics.

resultsSerum ATX was higher in females than in males. After controlling for sex, serum ATX correlated with multiple measures of adiposity and glucose homeostasis/insulin action. Serum ATX and BMI also independently predicted glucose infusion rate during a hyperinsulinemic euglycemic clamp and homeostatic model assessment of insulin resistance after controlling for sex and medication use.

conclusionsSerum ATX correlates with and predicts measures of glucose homeostasis and insulin sensitivity in older humans, suggesting that it may be a potential pathogenic factor and/or diagnostic/therapeutic target for insulin resistance in this population.
