The Efficacy of Using Video Laryngoscopy on Tracheal Intubation by Novice Physicians.

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
introductionThe first successful attempt at tracheal intubation with minimal complications is crucial for emergency physicians. The aim of this study was to compare endotracheal intubation using video laryngoscopy versus direct laryngoscopy in the emergency department by emergency medicine residents. MATERIALS AND
methodsIn this randomized clinical trial, 70 patients requiring laryngeal intubation were randomly enrolled in direct and video laryngoscopy groups. The first attempt success rate, frequency of attempts, complications, and hemodynamic changes after laryngoscopy were assessed. The data were analyzed using the Chi-square, independent t-test, and Fisher's exact test.
resultsThe results showed a significant increase in heart rate, as well as systolic and diastolic blood pressure after both direct and video laryngoscopy (P<0.001). However, this increase was more severe in the video laryngoscopy group (P<0.001).
conclusionAlthough the use of both devices had similar success rate, if orotracheal intubation is performed by a novice emergency medicine residents, direct laryngoscopy causes fewer hemodynamic effects on patients, compared to video laryngoscopy.
