Reference equations for oscillometry in adults: data from the Austrian LEAD study.
Article in ERJ open research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Determination of reference values of respiratory impedance ( Methods: Healthy asymptomatic never-smoking adults of the Austrian LEAD study cohort were included in the analysis. Healthy never-smoking adults without any respiratory disease, with normal weight (body mass index (BMI) ≤35 kg·m Results: A total of 887 participants were included in the analysis. We developed sex-specific reference equations for 30 total and within-breath oscillometry parameters. Height, age and BMI were included in the modelling, and height showed the strongest association. Predicted values showed a narrower normality range compared with existing reference equations. Conclusion: Our study provides highly accurate, adult reference equations derived from a large sample size with a wide age span. Development of reference equations supports further research on positioning of oscillometry in respiratory diagnostics.
