Lung function assessment by electrical impedance tomography among obese patients.
Article in Scientific reports, 2025. 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
Obesity is a growing problem worldwide. It is well reported that obesity is associated with various degrees of respiratory function compromise, which could be contributed by mechanical factors as well as co-morbid diseases such as asthma. While spirometry is the gold standard for lung function measurement, it does have the drawback of only being able to measure the global function of the lungs and is uncomfortable for those with difficulty using a large degree of effort. A prospective cross-sectional study was conducted in Queen Mary Hospital, Hong Kong to recruit Chinese obese and non-obese subjects, to compare and correlate the lung function parameters measured by electrical impedance tomography (EIT) and spirometry. Obesity was diagnosed based on the local definition of body mass index of 25 kg/m
