Interdevice agreement in respiratory resistance values by oscillometry in asthmatic children.
Article in ERJ open research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04903145 (Proof-of-concept of the Measurement of Lung Function Using the Relaxed Expiratory Occlusion Monitor), which is not on this map. Cited by 11 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
backgroundWith several commercially available devices measuring respiratory impedance by oscillometry, the agreement between values obtained on different instruments or frequencies remains unclear. Our aim was to examine the agreement between resistance and reactance parameters on two oscillometry instruments using different waveforms.
methodsWe conducted a prospective cross-sectional study in asthmatic children aged 3-17 years. Reproducible oscillometry measurements were obtained in random order, by blinded operators, at three modes: 5-10-15-20-25 Hz (5-25 Hz) multifrequency mode on the MasterScreen impulse oscillometry system, and both 5-25 Hz multifrequency mode and 7 Hz monofrequency on the tremoFlo C-100 airwave sinusoidal system. Resistance, reactance and within-breath parameters were examined using the intraclass correlation coefficient (ICC), paired t-test, linear regression and Bland-Altman method.
resultsOf 50 participants, 44 and 38 completed between-device and within-frequency measurements, respectively. Between-device measurements at 5-25 Hz showed high (ICC 0.88-0.91) and good (ICC 0.69-0.87) agreement in resistance and reactance, respectively, but with an absolute within-patient difference (≥0.05 kPa·L
conclusionObserved differences in resistance and reactance suggest the need for instrument- and frequency-specific paediatric normative values.
