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
purposeThe study aimed to evaluate whether the relative height (RH) of the entry point (EP) during CT-guided lung biopsies, adjusted for patient positioning, can predict the risk of pneumothorax during the intervention, leveraging the gravitational effects on pleural pressure. MATERIALS AND
methodsWe retrospectively analyzed 128 percutaneous CT-guided lung biopsies performed at a single center between January 2018 and December 2023. Patients were grouped based on pneumothorax occurrence. Various measurement methods indirectly assessed the influence of gravitational force on pleural pressure, focusing on the RH at the EP with prone positioning adjustments (PP). Other confounding factors like patient demographics, lesion characteristics, pre-puncture fluid administration and other procedural details were assessed. Test performance metrics were compared using Chi-Square, Fisher's exact, and Mann-Whitney U tests. Univariate and binomial logistic regression assessed the influence of different parameters on pneumothorax occurrence.
resultsAll measurements of lower RH at EP and pre-puncture fluid administration were significantly associated with a reduced incidence of peri-interventional pneumothorax (p < 0.01). The RH at EP adjusted for the prone position demonstrated the best predictive performance (AUC = 0.844). After adjusting for various confounding factors, both lower RH at EP adjusted for the prone position (OR 110.114, p < 0.001) and pleural fluid administration (OR 0.011, p = 0.011) remained independently associated with a lower risk of pneumothorax.
conclusionStrategic use of gravity by selecting the lowest possible entry point, ideally positioning the patient laterally, combined with pre-puncture pleural fluid administration, could be the key to reducing pneumothorax in CT-guided lung biopsies.
