Impact of ventilation strategy on recurrence patterns after pneumothorax surgery: a stratified analysis by lung dystrophy.
Article in Journal of thoracic disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Pneumothorax surgery is typically performed under one-lung ventilation (OLV); however, two-lung ventilation (TLV) may reduce volumetric stress on the contralateral lung, potentially lowering subsequent contralateral pneumothorax and shorten overall operation time thus we compared recurrence patterns of pneumothorax under two different ventilation strategies and defined likelihood of recurrence based on lung dystrophy and evaluated the feasibility of TLV. Methods: This study retrospectively analyzed 180 primary spontaneous pneumothorax (PSP) patients who underwent thoracoscopic surgery utilizing two different ventilation methods. Preoperative CT scans were used to calculate the Dystrophic Severity Score (DSS), and a subgroup analysis was conducted to evaluate the association between the extent of lung dystrophy and the risk of pneumothorax recurrence. Results: One hundred and forty-five patients received pneumothorax surgery under OLV and 35 underwent surgery under TLV and all patients showed similar baseline characteristics. The TLV group showed shorter induction and operation time (20 Conclusions: Higher preoperative DSS showed strong association with postoperative recurrence, especially on contralateral recurrence when TLV was utilized. Therefore, using the DSS for preoperative risk stratification to guide the selection of an optimal ventilation strategy may be important and could be considered for improving surgical outcomes in pneumothorax treatment.
