Predictive risk factors of failed laryngeal mask airway insertion at first attempt.
Article in The Journal of international medical research, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Objectives A failed first attempt at laryngeal mask airway (LMA) insertion could increase the risk of laryngospasm, hypoxemia, and postoperative sore throat. This study was performed to investigate the risk factors for failed first-attempt LMA placement. Methods In total, 461 patients who underwent general anesthesia with a Supreme LMA (Teleflex Medical, Shanghai, China) and who had an American Society of Anesthesiologists (ASA) physical status of I to III were prospectively enrolled. The LMA was inserted after anesthetic induction. We recorded the insertion conditions and each patient's age, ASA status, body weight, body mass index (BMI), duration of anesthesia, size of LMA, and cuff pressure; the years of work experience of the anesthesiologists; and the use or nonuse of lidocaine gel as a lubricant. Results Successful first-attempt placement of the Supreme LMA was achieved in 438 (95.10%) patients, while first-attempt placement failed in 23 (4.99%). Significant risk factors for failure of first-attempt LMA insertion included high age, high body weight, BMI of <20 kg/m
