[Clinical-radiological-pathological Characteristics of 297 Cases of Surgical Pathology Confirmed Benign Pulmonary Lesions in Which Malignancy Could Not Be Excluded in Preoperative Assessment: A Retrospective Cohort Analysis in a Single Chinese Hospital].

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
backgroundLow dose computed tomography (LDCT) for lung cancer screening is widely employed in China as a result of increasing cancer screening awareness. Although some pulmonary lesions detected by LDCT are cancerous, most of the pulmonary nodules are benign. It is important to make effective preoperative differentiation of pulmonary lesions and to obviate the need for surgery in some patients with benign disease.
methodsFrom January 1, 2017 to December 31, 2018, patients in our institution with surgical pathology confirmed benign pulmonary lesions in which malignancy could not be excluded in preoperative assessment were enrolled in this study. Retrospective analysis of clinical data was conducted.
results297 cases were collected in this study. Prevalence of benign disease in patients underwent resection for focal pulmonary lesions is 9.8% in our institution. In 197 patients (66.3%), pulmonary lesions were detected by LDCT screening. A total of 323 assessable pulmonary lesions were detected by chest CT. The average diameter of pulmonary lesions was (17.9±12.1) mm, and 91.0% of which were greater than or equal to 8 mm. Solid nodules accounted for 65.6% of these lesions. Imaging characteristics suggesting malignancy were common, including spicule sign (71/323, 22.0%), lobulation (94/323, 29.1%), pleural indentation (81/323, 25.1%), vascular convergence sign (130/323, 40.2%) and vacuole sign (23/323, 7.1%). 292 patients (98.3%) underwent video-assisted thoracoscopic surgery (VATS). Pulmonary wedge resection was performed in 232 cases (78.1%), segmental resection in 13 cases (4.4%) and lobotomy in 51 cases (17.2%). Surgical complications occurred in 4 patients (1.3%). The most frequent findings on surgical pathology analysis were: infectious lesions in 98 cases (33.0%), inflammatory nodules in 96 cases (32.3%), and hamartoma in 64 cases (21.5%).
conclusionsSolid nodules accounted for most of these benign pulmonary lesions in which malignancy could not be excluded preoperatively, and imaging characteristics suggesting malignancy were common. VATS is an important biopsy method to identify etiology and pathology for lesions. The most frequent benign pulmonary diseases that are suspected to be malignant and underwent surgical resection are: infectious lesions, inflammatory nodules and hamartoma.
