1 · What the graph read from 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.

2 · The registry

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

PURPOSE AND

methodMany post-COVID patients suffer from dyspnea on exertion. To visualize exercise-induced dyspnea, a post-COVID patient and a healthy volunteer underwent an exercise test on a treadmill under stress relevant to everyday life monitored by electrical impedance tomography (EIT).

resultsThe lung-healthy volunteer showed an even ventilation distribution throughout the assessment, a large ventilated area, and a butterfly-like lung shape with a convex lung rim. The post-COVID patient showed clear differences in the ventilated area compared to the control subject. During exercise, a constantly changing picture of differently ventilated areas is shown. However, especially the anterior regions were under-ventilated and larger areas were partially absent from ventilation. Overall, uncoordinated breathing and an uneven distribution of ventilation dominated the findings.

conclusionEIT is suitable for visualizing disturbed ventilation of the lungs, both at rest and under stress. The potential as a diagnostic tool in dyspnea assessment should be investigated.
