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: Conventional video-assisted thoracoscopic surgery (VATS) under intubated general anesthesia poses significant risks in non-small cell lung cancer (NSCLC) patients with compromised pulmonary function, including postoperative pulmonary complications and respiratory failure. Non-intubated spontaneous ventilation video-assisted thoracoscopic surgery (NIVATS), which avoids one-lung ventilation (OLV) and airway instrumentation, may mitigate these risks and accelerate recovery. However, concerns remain regarding intraoperative hypoxemia, hypercapnia, and mediastinal flutter. This study aimed to evaluate the feasibility and safety of NIVATS as an alternative to intubated VATS in carefully selected NSCLC patients with impaired pulmonary function to facilitate enhanced recovery after surgery (ERAS) in this specific population. Methods: A retrospective analysis was performed of 162 NSCLC patients with compromised pulmonary function who underwent either NIVATS (n=86) or intubated VATS (n=76) between January 2021 and May 2025. In the NIVATS group, 37 patients underwent lobectomy (48.7%) and 39 underwent segmentectomy or wedge resection (51.3%); in the VATS group, 46 underwent lobectomy (53.5%) and 30 underwent segmentectomy or wedge resection (46.5%). Propensity score matching (1:1) was performed to minimize confounding bias, yielding two balanced groups of 62 patients each. Short-term surgical outcomes were subsequently compared between the two groups. Results: After propensity score matching, no significant differences were observed between the NIVATS and VATS groups in terms of operative time, anesthesia duration, procalcitonin (PCT) levels, or cardiovascular complications. Conversely, NIVATS was associated with significantly improved outcomes in chest tube duration (2.66±3.35 Conclusions: For carefully selected NSCLC patients with compromised pulmonary function, NIVATS represents a feasible and safe alternative to conventional intubated VATS. By mitigating anesthesia-related trauma, NIVATS facilitates ERAS and expands the boundaries of surgical treatment for high-risk patients.
