Depression in children with asthma: Testing a cholinergically mediated "endotype".

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.
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
Background: Asthma is not a single uniform disease; instead, it comprises various disease sub entities, or "endotypes," with different etiologies and pathophysiologies. As asthma endotypes are discerned, individuals with asthma can be matched with optimal therapies for their specific asthma subtype. Depression is common in persons with asthma and associated with increased asthma-related morbidity and mortality. Depression in child asthma is associated with a predominance of parasympathetic/cholinergic activation over sympathetic activation. Cholinergic activity mediates airway smooth muscle constriction and has effects on airway inflammatory cells and mucus-secreting goblet cells. Objective: The goal of the current study was to examine whether children with asthma who have more depressive symptoms have cholinergically mediated disease that is differentially responsive to short-acting anticholinergic therapy. Methods: A total of 39 children with asthma (aged 7-17 years) and baseline obstruction on spirometry were evaluated for depressive symptoms by using the Children's Depression Inventory. Spirometry was used to evaluate the children for improvement in airway function following treatment with a short-acting anticholinergic medication. Inflammation was assessed by determining fractional exhaled nitric oxide levels and peripheral blood eosinophil counts, and atopic status was assessed by skin prick testing and measurement of total serum IgE level. Results: There was a statistically significant positive correlation between depressive symptoms and increase in FEV1 percent predicted value in response to ipratropium administration ( Conclusion: Higher depressive symptom scores are associated with increased airway responsiveness to inhaled ipratropium in children with asthma and active airway obstruction. These findings suggest the potential for definition of an endotype of asthma with comorbid depression that may benefit from anticholinergic asthma therapies.
