Is the BioSentry Tract Sealant System Effective in Reducing the Pneumothorax Rate After CT-Guided Transthoracic Lung Biopsy With an 18G Biopsy Needle?

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
introductionThis study evaluated whether the BioSentry Tract Sealant System (BTS) (Merit Medical Systems, South Jordan, Utah) reduces pneumothorax rates in CT-guided lung biopsies (CTLB) using an 18G biopsy/17G introducer needle. MATERIALS AND
methodsA total of 272 patients underwent CTLB between January 2015 and February 2019 using a 17G/18G system. BTS was used in 125 patients, while no pleural sealant was used in 147. The variables assessed included pneumothorax on post-biopsy CT images or chest X-ray, chest tube insertion, lesion size, pleura-to-lesion distance, and the presence of emphysema. The two groups were compared using T-tests with a significance level of 0.05.
resultsIn the BTS group, 23 subjects (18%) had a pneumothorax compared to 38 (26%) in the control group (p < 0.05). Four patients (17%) in the BTS group required a chest tube, compared to three patients (8%) in the control group (p = 0.28). The mean lesion size in patients with a pneumothorax was 1.62 cm in the BTS group and 2.44 cm in the control group (p = 0.27). The mean pleura-to-lesion distance in those with pneumothorax was 2.23 cm in the BTS group and 1.52 cm in the control group (p = 0.17). Emphysema was present in 47% of patients in the BTS group and 30% in the control group (p < 0.05).
conclusionBTS reduced pneumothorax rates in CTLB patients using a 17G/18G system, despite a higher proportion of emphysema patients in the BTS group. No significant difference in the rate of chest tube insertion was observed with or without BTS, which contrasts with previous studies where 19G/20G biopsy systems were used.
