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: Low-dose computed tomography screening has substantially improved the detection of peripheral pulmonary lesions (PPLs). Ultrasound-guided lung biopsy is widely used for diagnosis; however, postoperative hemoptysis is a critical complication, and the value of routine prophylactic hemostasis remains unclear. This study aimed to investigate the risk factors for hemoptysis following ultrasound-guided percutaneous lung biopsy and evaluate the advantages and disadvantages of prophylactic hemostatic agents in high- and low-risk patients. Methods: A total of 697 patients who underwent ultrasound-guided peripheral lung biopsy were retrospectively enrolled in this study. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for postoperative hemoptysis, and receiver operating characteristic curve analysis was used to determine the optimal cutoff value for lesion thickness. Subsequently, 126 patients were prospectively recruited and randomly divided into four subgroups: high-risk with hemostatic agents, high-risk without hemostatic agents, low-risk with hemostatic agents, and low-risk without hemostatic agents. Quantitative perioperative indicators, including hemoptysis incidence and volume, blood oxygen saturation, pulse rate, hemoglobin, platelet count, and coagulation function indices, were statistically compared among groups, and hemostatic agent-related adverse complications were recorded. Results: The overall post-biopsy hemoptysis rate was 9.03% (63/697). Multivariate regression analysis confirmed that lesion thickness <15 mm and grade 2 air bronchial signs were independent risk factors for hemoptysis (all P<0.05). The optimal cutoff value of lesion thickness was 15 mm, with an area under the curve (AUC) of 0.713, a sensitivity of 92.4%, and a specificity of 52.4%. For high-risk patients, prophylactic hemostatic agents significantly reduced the hemoptysis rate (15.15% Conclusions: Lesion thickness <15 mm and grade 2 air bronchial signs were identified as independent risk factors for hemoptysis following ultrasound-guided biopsy of PPLs. Prophylactic hemostatic agents may help reduce the hemoptysis rate and volume in patients with at least one high-risk factor. However, given the moderate predictive performance of these risk factors (AUC =0.713), individualized clinical judgment remains essential.
