Predictive factors for prolonged hospitalization related to pneumothorax after CT-guided transthoracic needle biopsy.

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
backgroundPneumothorax is consistently reported as the most prevalent complication of computed tomography-guided transthoracic needle biopsy. While most cases of pneumothorax resolve with conservative management strategies, some cases are linked to a more protracted clinical trajectory necessitating active intervention. However, few reports have described the clinical and procedural determinants of prolonged hospitalization after post-biopsy pneumothorax.
methodsThis retrospective study analyzed 1,457 CT-guided TTNB procedures performed at a tertiary referral center between January 2021 and December 2025. The incidence of post-biopsy pneumothorax was 20.5%. Among 82 patients with prolonged hospitalization due to pneumothorax, their management strategies were categorized into two groups: (1) high-concentration oxygen therapy (n = 54) and (2) invasive interventions, including percutaneous catheter drainage (PCD) or chest tube insertion (n = 28). Logistic regression models with backward selection were used to identify predictive factors for prolonged hospitalization.
resultsAmong the 82 patients with prolonged hospitalization due to pneumothorax, the median age was 75 years and 75.6% were male. In multivariable analysis, a lower diffusing capacity for carbon monoxide (DL
conclusionsIn patients with post-biopsy pneumothorax, impaired pulmonary function may be linked to a prolonged clinical course. Incorporating these pre-procedural physiological markers may facilitate improved risk stratification and optimized hospital resource allocation.
