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

Atopic dermatitis (AD), or eczema, is estimated to affect more than 30 million people in the United States, with over 6 million have moderate or severe disease. Chronic pruritus is a common symptom and is one of most difficult to manage. Even though itch is a major component in the pathology of AD, the biological underpinnings are not fully understood. In the present manuscript we identify a role for the neutrophil receptor, Mrgpra2, in the development of AD hyperplasia and chronic itch in the mouse. The role of Mrgprs in the context of itch have provided a huge step in our understanding of pruritus and have led to the development of novel therapeutics. Here we provide new evidence for the involvement of Mrgpra2 in the development of AD. Here we show that genetic deletion of Mrgpra2 significantly reduces scratching behaviors, transepidermal water loss, epidermal thickening, and Tslp expression in AD.
