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

beta-adrenergic receptors (betaARs) relax airway smooth muscle and bronchodilate, but chronic beta-agonist treatment in asthma causes increased sensitivity to airway constriction (hyperreactivity) and is associated with exacerbations. This paradox was explored using mice with ablated betaAR genes (betaAR-/-) and transgenic mice overexpressing airway smooth muscle beta2AR (beta2AR-OE) representing two extremes: absence and persistent activity of airway betaAR. Unexpectedly, betaAR-/- mice, lacking these bronchodilating receptors, had markedly decreased bronchoconstrictive responses to methacholine and other Gq-coupled receptor agonists. In contrast, beta2AR-OE mice had enhanced constrictive responses. Contraction to permeabilization with beta-escin was unaltered by gene ablation or overexpression. Inositol phosphate accumulation by Gq-coupled M3-muscarinic, thromboxane-A2, and 5-HT2 receptors was desensitized in airway smooth muscle cells from betaAR-/- mice and sensitized in cells from beta2AR-OE mice. Thus, betaAR antithetically regulates constrictive signals, affecting bronchomotor tone/reactivity by additional means other than direct dilatation. Studies of signaling elements in these pathways revealed the nodal point of this cross talk as phospholipase C-beta1, whose expression was altered by betaAR in a direction and magnitude consistent with the physiologic and cellular responses. These results establish a mechanism of the beta-agonist paradox and identify a potential asthma modifier gene (phospholipase C-beta1), which may also be a therapeutic target in asthma when chronic beta-agonists are required.
