Individualized regulation of inflatable laryngeal mask airway cuff pressure reduces postoperative pharyngolaryngeal pain in elderly patients: a randomized controlled trial.
Trial report in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06954857 (The Influence of Standardized Process Management of Laryngeal Mask Airway Placement Based on Pressure Monitoring on the Incidence of Adverse Reactions in Elderly Patients During the Perioperative Period), which is not on this 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.

Abstract
Background: Inflatable laryngeal mask airway (ILMA) cuff pressure lacks routine monitoring and standardized safe thresholds, with clinical practice often referencing manufacturer specifications. Empirical inflation in clinical practice often leads to overinflation and increased pharyngolaryngeal complications. This study established an individualized ILMA cuff pressure regulation strategy based on physiological characteristics and sealing principles, aiming to compare its effect on postoperative pharyngolaryngeal pain in elderly patients with empirical inflation. Methods: This single-center, double-blind randomized controlled trial comprised 78 elderly patients undergoing general anesthesia with ILMA. Patients were randomly assigned to either the empirical inflation (EI) group or the individualized regulation and real-time monitoring (RM) group. In group EI, the cuff was inflated empirically. In group RM, individualized regulation and real-time monitoring were applied: cuff pressure was adjusted to maintain ≥ peak airway pressure, with the oropharyngeal leak pressure (OLP) ≥ 25 cmH Results: 78 elderly patients were randomized, and 74 completed the study. Cuff pressure was significantly higher in group EI than in group RM ( Conclusion: In elderly patients undergoing ILMA-assisted general anesthesia, empirical inflation may result in unnecessarily high cuff pressure. Individualized cuff pressure regulation can reduce postoperative pharyngolaryngeal pain and mucosal injury without compromising ventilation seal integrity, and may represent a feasible strategy to optimize ILMA management in elderly patients.
