1 · What the graph read from 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.

2 · The registry

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

backgroundVideo laryngoscopy has been associated with some orotracheal intubations and enhances the glottic view at time of laryngoscopy and the success rate of the intubation in patients from the emergency department and the intensive care unit. In usual cases, direct laryngoscopy is performed among the patients from the emergency department or the intensive care unit. In this systematic review and meta-analysis, we draw the comparison between the video laryngoscopy and direct laryngoscopy for the emergency orotracheal intubation.

objectiveThe objective of the study was to identify the clinical efficacy of video laryngoscopy versus laryngoscopy for emergency orotracheal intubation. MATERIALS AND

methodsMEDLINE, CENTRAL, EMBASE, and Web of Science databases were analyzed from 2003 to 2020. Keywords used for searching the studies were "laryngoscopy," "video laryngoscopy," "direct laryngoscopy," "emergency department," "intensive care unit," "orotracheal," "video laryngoscope," "glidescope," "airway scope," "airway," "Macintosh laryngoscopy," "airway management," "tracheal intubation," "orotracheal intubation," and "intubation."

resultsThe first-pass intubation success rates in the intensive care unit were low in video laryngoscopy with 95% CI 1.21 (1.13-1.30) and heterogeneity

conclusionNo significant efficiency was noticed in using video laryngoscopy when compared with direct laryngoscopy with the available data. The data reported in studies are not enough for efficient clinical analysis of the benefits of using video laryngoscopy over direct laryngoscopy. Thus, information such as length of stay, mortality, sever complications, and length of hospital stay must be reported.
