Comparison of impulse oscillometry measurements according to body mass index in patients with asthma.
Article in BMC pulmonary medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundObesity can lead to increased airway resistance, especially in the peripheral airways. Impulse oscillometry (IOS) may detect small airway changes in asthma. In this study, we aimed to investigate the effect of obesity on the small airways of the lungs in asthmatic patients by IOS measurements.
methodsOne hundred newly diagnosed asthmatic patients (28 male) were divided into three groups (BMI (< 25.0 kg/m
resultsThere was no detected significant difference concerning age, gender, smoking history, pack year, comorbidities (except hypertension and anxiety), asthma cardinal symptoms (except dyspnea), and pulmonary function tests among groups (p > 0.05). There were significant differences regarding R5, R5%, R20%, X5, X20, Fres, and R5-R20 among the three groups. Group 1 significantly differed about R5-R20, X5, AX, and Fres compared to groups 2 and 3 in pairwise comparisons. Based on these results, a difference was detected between BMI < 25 and ≥ 25. There was only one significant variable (R20%) between BMI < 30 and ≥ 30. When performing a correlation test between IOS parameters and BMI, it was observed to be significantly correlated (p < 0.05) except X5% and X20% (p > 0.05).
conclusionObesity and being overweight affected peripheral airways and reactance; however, obesity also affects central airways, based on our results. In addition, it was thought that IOS may detect earlier than PFTs on small airway changes.
