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

backgroundAsthma prevalence decreases postpuberty in males. Testosterone inhibits airway smooth muscle contraction and attenuates type 2 inflammation.

objectiveTo investigate the relationship between serum testosterone and current asthma prevalence and lung function in a nationally representative data set.

methodsSerum testosterone and self-reported physician-diagnosed current asthma data were obtained from 7584 participants aged 6 to 80 years from the cross-sectional 2011-2012 National Health and Nutrition Examination Survey. We used logistic regression to test associations between testosterone and current asthma, adjusting for demographic characteristics and stratifying by sex and age; linear regression to evaluate correlations between testosterone and lung function among patients with asthma; and interaction terms to test for effect modification by blood eosinophils and fractional exhaled nitric oxide.

resultsSerum testosterone inversely associated with odds of current asthma in both men and women, but this association was nonlinear. Similar protective effect sizes were observed for both sexes after log

conclusionsSerum testosterone inversely associates with current asthma prevalence regardless of sex and correlates with better lung function in a nationally representative database. Androgen therapy for asthma should be further investigated.
