Compatibility analysis of total lung capacity values measured by segmentation with computed tomography and helium dilution method.
Article in Annals of thoracic medicine. 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
backgroundAccurate assessment of lung volumes is essential for diagnosing ventilatory defects and managing pulmonary diseases such as interstitial lung diseases (ILDs) and chronic obstructive pulmonary disease (COPD). Although body plethysmography is the standard method, it can be limited by patient tolerance and complexity. Helium dilution method (HDM) is a portable and cost-effective alternative, while chest computed tomography (CT) offers noninvasive volume assessment through imaging. This study aimed to evaluate the agreement and potential interchangeability between TLC values measured by CT (TLC MATERIALS AND
methodsIn this retrospective study, patients who underwent HDM and chest CT were evaluated. Based on pulmonary function tests (PFTs), patients were grouped as having restrictive or obstructive ventilatory defects. TLC

conclusionBoth HDM and CT provide valuable lung volume data. CT may serve as a reliable alternative in patients unable to undergo PFTs. Prospective studies are warranted to confirm clinical utility.
