Patterns of lung aeration assessed through electrical impedance tomography in paediatric patients undergoing elective surgery: insights from a prospective and observational data-registry.
Article in Journal of anesthesia, analgesia and critical care, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundThe impact of anaesthesia on lung function during paediatric surgery remains an area of active investigation. Understanding respiratory mechanics under different anaesthetic approaches is crucial for optimising pulmonary management in this vulnerable population.
objectiveTo assess ventilation distribution changes during different phases of anaesthesia in paediatric patients, using electrical impedance tomography (EIT).
methodsThis observational study included 76 paediatric surgical patients-57 under controlled mechanical ventilation (CMV) and 19 breathing spontaneously. EIT assessed lung ventilation at multiple timepoints (T1-T6), analyzing regional distribution (ROIs) and center of ventilation (CoV).
resultsIn the CMV group, ventilation progressively shifted toward ventral lung regions (p < 0.0001 from T1 to T2, T3, T4, T5) with a contemporaneously reduced ventilation switching from T1 to T2 (p = 0.005), T3 (p < 0.0001), T4 (p = 0.001), and T5 (p < 0.0001). Ventilation normalised upon restoration of spontaneous breathing at the end of surgery. In the same group, CoV shifted toward non-dependent lung regions from T1 to T2, T3, T4, and T5 (p < 0.0001) and returned to baseline at T6. Overall, no modifications were observed in the spontaneous breathing group.
conclusionsIn paediatric surgical patients, contrariwise to spontaneous breath where no modifications occurred, CMV induced a progressive redistribution of ventilation towards the ventral lung regions, at the expense of the dorsal zones. These changes were reversible with the recovery of spontaneous breathing.
