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

purposeEndotracheal intubation is a critical skill in anesthesia, particularly for patients with compromised airways. This randomized pilot study evaluated the feasibility and impact of the Infrared Red Intubation System (IRRIS

methodsThirty patients were randomized into two groups: one with the IRRIS device and one without (control). The primary outcome was the impact of IRRIS on first-pass success. Secondary outcomes included glottic visibility, intubation time, and adverse effects.

resultsResults showed that both groups demonstrated nearly identical percentages of glottic opening (POGO) and glottic entrance visibility, achieving successful intubation on the first attempt. Although the IRRIS group had a slightly longer intubation time and more instances of required external manipulation, the vocal cords were not visible without IRRIS in the most obese patient in our cohort.

conclusionThe IRRIS device effectively illuminated the laryngeal inlet, enhancing differentiation from surrounding structures, such as the esophagus. This study suggests that IRRIS may be a valuable adjunct for video laryngoscopy in patients with difficult airways, though further research is needed to assess its broader applicability.

backgroundEndotracheal intubation in patients with compromised airways is a notoriously complex and daunting task for anesthesiologists. Throughout the years, numerous supportive techniques and innovative equipment have been developed to address this challenge. This randomized clinical study sheds light on the potential benefits of utilizing an external pre-cricoid emitting infrared light source, the 'Infrared Red Retrograde Intubation System' (IRRIS
