A Prospective Crossover Study Evaluating the Efficacy of King Vision Video Laryngoscope in Patients Requiring General Anesthesia with Endotracheal Intubation.
Article in Anesthesia, essays and researches. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis 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
backgroundDirect laryngoscopy used for tracheal intubation requires aligning the pharyngeal, laryngeal and oral axes to achieve a line of sight. Video laryngoscopy provides a better view of the glottis without the need for aligning the three axes.
aimsTo evaluate the effectiveness of King vision laryngoscope over Macintosh laryngoscope in visualizing the glottis and intubating the trachea, when used on a same patient as in a cross over manner. SETTINGS AND
designDepartment of Anaesthesia, Mediciti Institute of Medical Sciences, prospective crossover study conducted over a period of six months. SUBJECTS AND
methodsSixty adult patients belonging to ASA physical status class I-II, requiring tracheal intubation were randomly assigned to intubation by King vision or Macintosh laryngoscope. Improvement, if any, in the Cormack-Lehane grading using the King vision scope, following initial grading with the Macintosh blade in the same patient was analyzed. STATISTICAL ANALYSIS: Mean and Standard deviation were calculated for different parameters under the study. Where appropriate, results were analyzed using the Mc Nemar χ2 test. A 'p' value less than 0.05 was considered statistically significant.
resultsIn the King Vision group, Cormack and Lehane grade improved in the majority (9/12) of patients in whom the initial Cormack and Lehane grade was >1 using the Macintosh blade.
conclusionsThe use of the King vision blade significantly improved the laryngoscopic view over the Macintosh blade but the time for intubation was prolonged.
