Integrated pulmonary index (IPI)-guided ventilation management during "tubeless" video-assisted thoracoscopic surgery under general anesthesia: a case report.
Article in Frontiers in medicine, 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
Background: "Tubeless" anesthesia for video-assisted thoracoscopic surgery (VATS) maintains spontaneous ventilation but complicates respiratory monitoring. The integrated pulmonary index (IPI) is a non-invasive tool that assesses respiratory status by integrating four real-time parameters [EtCO Case presentation: We present a 42-years-old female who underwent right middle lobectomy under tubeless anesthesia with continuous IPI monitoring. Anesthesia was maintained via laryngeal mask airway with spontaneous ventilation, supplemented by total intravenous anesthesia and paravertebral blockade. The IPI system facilitated tiered respiratory management: IPI ≤ 6 signaled acute respiratory events, while IPI ≤ 4 necessitated immediate assisted ventilation intervention. Real-time IPI tracking ensured respiratory stability (target range 8-10, EtCO Conclusion: This case demonstrates IPI's efficacy in detecting early ventilatory compromise during tubeless VATS, enabling proactive intervention without compromising surgical advantages. Further refinement of IPI thresholds may enhance perioperative safety in spontaneous ventilation anesthesia.
