Comparison of Brimacombe score and first-attempt success rate of intubation through Ambu AuraGain and i-gel in anaesthetized adult patients: A prospective open-label study.
Article in Journal of anaesthesiology, clinical pharmacology. 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 and Aims: Second-generation supraglottic airway devices (SAD), such as i-gel and Ambu AuraGain, offer higher sealing pressures and facilitate intubation. Although literature exists on their ventilatory characteristics, limited data are available on their performance as intubation conduits in the adult Indian population. The purpose of this study was to shed light on the clinical performance and intubation characteristics of both devices. Material and Methods: In this prospective, open-label study, 96 ASA I and II patients aged 18-60 years undergoing elective surgeries were equally randomized into Group A (Ambu AuraGain) and Group I (i-gel). All SADs were inserted under general anaesthesia using standard techniques. Outcomes included the Brimacombe score (primary), first-attempt success rate of SAD insertion, oropharyngeal leak pressure (OLP), ease of gastric tube insertion, success rate of intubation through SAD, intubation time, size of the endotracheal tube used, ease of intubation, and adverse events. Results: Ambu AuraGain exhibited a superior Brimacombe score when assessed via fibreoptic bronchoscope ( Conclusions: I-gel and Ambu AuraGain demonstrated similar effectiveness in ventilation characteristics. However, Ambu AuraGain facilitated easier endotracheal intubation via SAD in anesthetized adults, owing to its ability to accommodate larger endotracheal tubes compared to i-gel.
