Monitoring of Regional Ventilation Distribution Using Electrical Impedance Tomography in Pediatric Patients With Chest Physiotherapy-A Feasibility Study.
Article in Pediatric pulmonology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundCurrent evidence remains unclear whether pediatric patients with acute or chronic lung diseases benefit from chest physiotherapy (CPT) during spontaneous breathing. Electrical impedance tomography (EIT) offers the opportunity to assess treatment effects of CPT on regional ventilation distribution.
methodsWe conducted a prospective feasibility study between 10/2023 and 05/2024. Pediatric patients with need for active or passive CPT were screened. EIT measurements were performed immediately before CPT intervention (T1), and within 30 min after CPT intervention (T2).
resultsOverall, 25 patients were enrolled, with two patients enrolled twice at different admissions, resulting in a total of 54 EIT-measurements. The mean horizontal center of ventilation (CoVx) and the mean vertical CoVy were equally distributed at T1 and T2, without any difference seen when subdividing for mode of CPT. The mean global inhomogeneity index (GI) decreased from 0.38 to 0.36 (∆GI: -6%, p = 0.939) in the overall cohort, with a significant decrease between T1 and T2 in patients with active (∆GI: -10%, p = 0.015), but not in patients with passive CPT (∆GI: +6%, p = 0.199). In patients with a localized pulmonary finding in the radiological assessment (n = 10) we observed an increase in the ventilated lung area (EIT-pixel) of the affected lung side after CPT (T1: 141 vs. T2: 176; p = 0.128).
conclusionEIT seems feasible to monitor changes in regional ventilation distribution after CPT in pediatric patients. Patients with localized pulmonary radiological findings and patients after active CPT appear to benefit most from CPT, whereas there is a subset of individuals with no response to CPT.
