Long-term recurrence after surgery for recurrent primary spontaneous pneumothorax: pleural intervention versus surgical access.
Article in Updates in surgery, 2026. 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
The relative contributions of pleural intervention and surgical access to long-term recurrence after surgery for recurrent primary spontaneous pneumothorax remain uncertain. In this single-center retrospective cohort study, 315 patients younger than 35 years who underwent surgery for recurrent primary spontaneous pneumothorax after a second ipsilateral episode were included. Surgical treatment consisted of wedge resection combined with pleural abrasion or pleurectomy, performed through uniportal video-assisted thoracoscopic surgery or muscle-sparing mini-thoracotomy. The primary endpoint was recurrence-free survival. Kaplan-Meier analysis and Cox proportional hazards models were used to identify factors associated with postoperative recurrence. Overall recurrence occurred in 31 of 315 patients (9.8%) during a median follow-up of 64 months (IQR, 62-66); all included patients had at least 5 years of available follow-up. Recurrence was more frequent after pleural abrasion than after pleurectomy (14.4% vs. 4.7%, p = 0.004). In multivariable analysis, pleurectomy was independently associated with a lower hazard of recurrence than pleural abrasion (hazard ratio 0.255, 95% confidence interval 0.108-0.598; p = 0.002), whereas surgical access was not independently associated with recurrence-free survival (hazard ratio 1.023, 95% confidence interval 0.487-2.146; p = 0.953). Larger bullae, multiple bullae, and lower body mass index also remained independently associated with recurrence. Minimally invasive access was associated with more favorable perioperative recovery. In recurrent primary spontaneous pneumothorax, long-term recurrence appears to be more strongly associated with the pleural intervention strategy and baseline disease burden than with the route of surgical access. Pleurectomy was associated with lower recurrence, whereas minimally invasive access was associated with more favorable perioperative recovery.
