Body mass index and thoracic morphology parameters as predictors of pneumothorax in CT-guided lung biopsies.
Article in Polish journal of radiology, 2026. 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
Purpose: This study aimed to investigate whether body composition and thoracic morphology parameters could serve as predictors of pneumothorax risk in patients undergoing computed tomography (CT)-guided lung biopsies. Material and methods: We retrospectively analyzed 147 percutaneous CT-guided lung biopsies performed between January 2019 and December 2023, categorizing patients into groups with and without pneumothorax. Indirect assessment methods for body composition, including body mass index (BMI) and thoracic morphology parameters, were evaluated alongside confounding factors such as access route (AR) through dependent lung areas (DA), patient demographics, lesion characteristics, and procedural details. Statistical analyses included chi-square, Fisher's exact, and Mann-Whitney Results: BMI ≥ 27.5 ( Conclusions: Constitutional factors such as higher BMI or the identification of subclinical chest deformities on pre-procedural imaging may facilitate stratification into lower-risk categories, facilitating more precise and confident procedural planning. Especially in the absence of these protective factors, ensuring that the AR traverses the DA becomes particularly important for minimizing the risk of pneumothorax during CT-guided lung biopsies.
