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

Copper (Cu) is an essential cofactor for a variety of metabolic functions, and the regulation of systemic Cu metabolism is critical to human health. Dietary Cu is absorbed through the intestine, stored in the liver, and mobilized into the circulation; however, systemic Cu homeostasis is poorly understood. We generated mice with a cardiac-specific knockout of the Ctr1 Cu transporter (Ctr1(hrt/hrt)), resulting in cardiac Cu deficiency and severe cardiomyopathy. Unexpectedly, Ctr1(hrt/hrt) mice exhibited increased serum Cu levels and a concomitant decrease in hepatic Cu stores. Expression of the ATP7A Cu exporter, thought to function predominantly in intestinal Cu acquisition, was strongly increased in liver and intestine of Ctr1(hrt/hrt) mice. These studies identify ATP7A as a candidate for hepatic Cu mobilization in response to peripheral tissue demand, and illuminate a systemic regulation in which the Cu status of the heart is signaled to organs that take up and store Cu.
