Comparison of pulmonary dynamic compliance between Laryngeal Mask Airway Supreme
Article in Trials, 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
backgroundDuring laparoscopic cholecystectomy, pneumoperitoneum reduces pulmonary compliance, which may result in atelectasis and postoperative hypoxia. The efficacy of laryngeal mask ventilation during laparoscopic surgery is currently up for dispute. The objective of this study is to determine whether a Laryngeal Mask Airway Supreme™ (LMA-S) is non-inferior to an endotracheal tube (ETT) in maintaining lung compliance among low-risk patients undergoing laparoscopic cholecystectomy. The findings could be applied to implement novel airway management strategies for laparoscopic cholecystectomy procedures.
methodsA total of 100 American Society of Anaesthesiologists Classification (ASA) I-II patients will be randomly allocated to airway management with an LMA-S (L group, n = 50) or an ETT (T group, n = 50). After the induction of general anaesthesia, patients in group L will receive LMA-S, while patients in group T will receive ETT. Lung-protective ventilation strategy (LPVS) will be employed throughout the procedure in both groups. The primary outcome is pulmonary dynamic compliance (Cdyn) 15 min after pneumoperitoneum and up-head position. Secondary outcomes include the oxygenation index (OI), peak inspiratory pressure (PIP), end-expiratory carbon dioxide (EtCO DISCUSSION: This study will evaluate the effects of LMA-S ventilation on Cdyn and oxygenation in patients undergoing laparoscopic cholecystectomy. Clinical evidence to optimize airway management strategies for low-risk patients undergoing laparoscopic cholecystectomy will be provided by the results.
