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
Objective: To compare the application of the SaCo visual laryngeal mask and the WORK laryngeal mask in adult laparoscopic surgeries under general anesthesia, and to assess their effects on postoperative pharyngolaryngeal discomfort. Methods: A retrospective analysis was conducted on 90 adult patients who underwent elective laparoscopic surgery under general anesthesia between June 2022 and April 2024. Based on the airway device used, patients were divided into the control group (n=45, WORK laryngeal mask) and the observation group (n=45, SaCo visual laryngeal mask). The two groups were compared in terms of laryngeal mask insertion parameters (seal pressure, insertion time, first-attempt success rate, number of adjustments >2 times, peak airway pressure, endoscopic visibility grading, positioning accuracy, removal time), vital signs (heart rate, mean arterial pressure), perioperative outcomes (post-extubation time, time to regular diet, postoperative hospital stay), VAS-based pharyngolaryngeal discomfort scores, and complication rates. Results: The observation group demonstrated significantly higher airway seal pressure at insertion, 1 hour, and 2 hours post-insertion (P<0.05). Adjustment rate >2 times was significantly lower, while positioning accuracy was significantly higher (P<0.05). No significant differences were found in heart rate or mean arterial pressure between groups. The observation group had significantly shorter post-extubation time, earlier diet resumption, and shorter hospital stays (P<0.05). Pharyngolaryngeal discomfort scores at 1, 3, and 7 days post-surgery were significantly lower in the observation group (P<0.05). The complication rate was also lower in the observation group (4.44%) than in the control group (20.00%) (P<0.05). Conclusion: Compared to the WORK laryngeal mask, the SaCo visual laryngeal mask offers better sealing and placement accuracy, reduces pharyngolaryngeal discomfort, and promotes faster postoperative recovery with fewer complications.
