Observational study in European radiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05636410 (Ultrasound Assessment of the Larynx and Trachea in the Neonatal Period), which is not on this map. Cited by 2 papers.

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.

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.

Abstract

objectiveUltrasonography is an accessible diagnostic tool that allows noninvasive examination of the larynx and trachea, thereby minimally disturbing patient comfort. Despite the interest of ultrasonographers in these organs, specific normative values for the dimensions of their structures have not been published. This prospective cohort study aimed to establish the normal sizes for the laryngeal and tracheal structures, as assessed using ultrasound, within a neonatal population. MATERIALS AND

methodsBetween 2022 and 2023, experienced sonographers conducted ultrasonographic examinations of the larynx and trachea on 300 healthy newborns of Caucasian descent born between 32 and 42 weeks of gestation. Dimensions of the larynx, thyroid cartilage, vocal folds, glottis, epiglottis, subglottic region, trachea, epiglottis, and infrahyoid muscles were measured.

resultsNormative values were determined for the specific structures of the larynx, trachea, and infrahyoid muscles. The normative sizes for the evaluated structures were determined separately for each sex because of the significant differences observed between the groups.

conclusionThe results of this study contribute to the advancement of knowledge regarding the structure and function of these organs and may play a crucial role in enhancing the quality of airway management for newborns. The published article serves as a summary of the data obtained from a study registered at ClinicalTrials.gov (identifier NCT05636410). KEY POINTS: Question There are no standards for the size of specific parts of the larynx and trachea in the neonatal population on ultrasound examination. Findings The article discusses the ultrasonographic norms for the dimensions of individual laryngeal and tracheal structures, developed based on the studies of 298 neonates. Clinical relevance Knowledge of ultrasound reference values for the size of laryngeal and tracheal structures facilitates the diagnosis of diseases of these organs and allows individualizing the approach to newborns, especially those requiring intensive care.
