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

backgroundIt is established that videolaryngoscopy improves intubation success rates and views compared with direct laryngoscopy. However, concerns regarding default adoption of videolaryngoscopy include a negative impact on skill acquisition for direct laryngoscopy. This study aimed to assess the utility of Macintosh videolaryngoscopy for teaching direct laryngoscopy.

methodsWe systematically searched MEDLINE and Embase databases for relevant randomised controlled trials, crossover, and observational studies. Two authors screened abstracts and full-text manuscripts for inclusion before extracting and cross-checking data. Critical outcomes included first-attempt success, overall success, and time to intubation, with trainee confidence and ease of guidance assessed as secondary outcomes. Meta-analysis was performed using random-effects models. Risk of bias was assessed using the Cochrane RoB-2 tool.

resultsWe identified 21 relevant studies, 10 of which assessed Macintosh videolaryngoscopy for teaching direct laryngoscopy. For first-attempt success, videolaryngoscopy outperformed direct laryngoscopy with a risk ratio (RR) of 1.16 ([95% confidence interval 1.07-1.25]; five studies; I

conclusionsVideolaryngoscopy appears to be an effective tool for teaching direct laryngoscopy. Its role as a preferred teaching tool should be considered. SYSTEMATIC REVIEW PROTOCOL: PROSPERO (CRD42023493366).
