Comparison of oropharyngeal leak pressure and clinical performance of LMA ProSeal™ and i-gel® in adults: Meta-analysis and systematic review.
Synthesis in The Journal of international medical research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 23 papers, 3 of them syntheses that pooled it.
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
backgroundA meta-analysis and systematic review of randomized controlled trials to compare the oropharyngeal leak pressure (OLP) and clinical performance of LMA ProSeal™ (Teleflex® Inc., Wayne, PA, USA) and i-gel® (Intersurgical Ltd, Wokingham, UK) in adults undergoing general anesthesia.
methodsSearches of MEDLINE®, EMBASE®, CENTRAL, KoreaMed and Google Scholar® were performed. The primary objective was to compare OLP; secondary objectives included comparison of clinical performance and complications.
resultsFourteen RCTs were included. OLP was significantly higher with LMA ProSeal™ than with i-gel® (mean difference [MD] -2.95 cmH2O; 95% confidence interval [CI] -4.30, -1.60). The i-gel® had shorter device insertion time (MD -3.01 s; 95% CI -5.80, -0.21), and lower incidences of blood on device after removal (risk ratio [RR] 0.32; 95% CI 0.18, 0.56) and sore throat (RR 0.56; 95% CI 0.35, 0.89) than LMA ProSeal™.
conclusionLMA ProSeal™ provides superior airway sealing compared to i-gel®.
