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
objectivesTracheal intubation using laryngoscopy is a fundamental skill, for an anesthesiologist. However, teaching this skill is difficult since Macintosh direct laryngoscope (DL) allows only one individual to view the larynx during the procedure. Hence, this study aimed to determine whether King Vision® videolaryngoscope (KVL) provides any advantage over direct laryngoscopy in teaching this skill to airway novices. MATERIALS AND
methodsIn this prospective randomized crossover study, Ethical Committee clearance was obtained from the institutional review board (MSRMC/EC/2017) and the study was registered with Clinical Trial Registry. After informed consent, 53 medical students were allotted to perform laryngoscopy and endotracheal intubation on a manikin by using either KVL or Macintosh DL. The participants first performed laryngoscopy with either KVL or Macintosh DL following a brief instruction and then crossed over to the second arm of the study to perform laryngoscopy using the other scope. The primary outcome measure was the time for successful endotracheal intubation. The secondary outcome measures were incidence of esophageal intubation (EI), excess application of pressure on maxillary teeth excess maxillary pressure, and success rate.
resultsMean time for endotracheal intubation was significantly faster using KVL than in DL (44.64 vs. 87.72 s;
conclusionThe KVL is a more effective tool to teach endotracheal intubation in comparison to Macintosh laryngoscope in airway novice medical students. Clinical trial registry India registration number: CTRI/2017/11/010491.
