Risk factors associated with air embolism following computed tomography-guided percutaneous lung biopsy: a retrospective case-control study.
Article in PeerJ, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Retrospective analysis to identify the risk factors for air embolism following computed tomography (CT)-guided percutaneous transthoracic needle biopsy (TNB). Methods: A retrospective analysis of patients who underwent CT-TNB at The First Affiliated Hospital of Zhengzhou University and Xuzhou Cancer Hospital from January 2017 to December 2021 was performed. A total of 21 factors relevant to air embolisms were collected. Risk factors associated with air embolisms were determined by the least absolute shrinkage and selection operator (LASSO). The receiver-operator characteristic (ROC) was used to assess the ability of these factors to identify air embolisms. Results: Of these 32,748 patients, 28 experienced air embolisms (19 at The First Affiliated Hospital of Zhengzhou University (incidence, 1.46%) and nine at Xuzhou Cancer Hospital (incidence, 0.69%); total incidence, 2.16%). Only seven patients exhibited symptoms (symptom rate, 25.00%). A total of 21 patients were asymptomatic at the time of swept-source CT. No deaths occurred. We found through univariate and multivariate analysis that eight out of these 21 factors are associated with the occurrence of air embolism. The area under the ROC curve was 0.721, indicating good predictive power ( Conclusion: Cough during the procedure, hemoptysis during the procedure, the distance between the mass and the pulmonary vein, the presence of a cavity in the lesion, lesion location, number of samples, abnormalities in the patient's coagulation mechanism, and the puncture position may be the risk factors for air embolism in CT-TNB.
