Laryngeal mask airway versus endotracheal tube for preventing postoperative atelectasis after laparoscopic surgery: a randomized controlled trial.
Trial report in Frontiers 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
Background: Postoperative atelectasis is a common and clinically significant complication of general anesthesia, particularly during laparoscopic surgery due to reduced lung compliance and diaphragmatic elevation. In this study, the effects of a laryngeal mask airway (LMA) and endotracheal tube (ETT) on postoperative atelectasis after laparoscopic surgery were compared, and a predictive model for lung injury was developed. We hypothesized that the use of a laryngeal mask airway would be associated with reduced postoperative atelectasis compared with endotracheal intubation in patients undergoing laparoscopic surgery. Methods: In this single-center, assessor-blinded randomized controlled trial (ChiCTR2400094097), 192 adults (American Society of Anesthesiologists physical status I-III) undergoing elective laparoscopy (gastrointestinal, biliary, hernia, or gynecologic procedures) were randomized to LMA ( Results: In total, 186 patients completed follow-up. The ETT group showed significantly higher postoperative LUS scores compared with the LMA group (8.1 ± 1.9 vs. 5.6 ± 2.4, Conclusions: In laparoscopic surgery, laryngeal mask airway use is associated with reduced postoperative atelectasis and pulmonary complications compared with endotracheal intubation. Intraoperative deterioration in lung compliance may serve as an early indicator of postoperative lung aeration impairment detected by lung ultrasound.
