Ultrasound mapping of soft tissue vascular anatomy proximal to the larynx: a prospective cohort study.
Article in Korean journal of anesthesiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundBleeding incidents during percutaneous dilatational tracheostomy are concerning, and most cases occur in patients with unrecognized and unanticipated anatomical variations in the vascular anatomy. However, the extent of this variation remains unclear. To address this knowledge gap, our study aimed to comprehensively map laryngeal vascular anatomy in a cohort of adult patients.
methodsUltrasound assessments of the soft tissue in the neck were performed, spanning from the thyroid cartilage to the third tracheal ring and extending 2 cm laterally on both sidesperformed. We subdivided this area into 12 zones comprising four medial and eight lateral sections. A pre-planned form was used to document the presence of arteries or veins in each zone. The results are reported as odds ratios, 95% CIs, and corresponding P values.
resultsFive-hundred patients were enrolled from August 14, 2023, to November 13, 2023, at the University Hospital of Padua. Arteries and veins were identified in all investigated zones (varying from a minimum of 1.0%-46.4%). The presence of invessels progressively increased from the cricothyroid membrane to the third tracheal ring and from the midline to the paramedian laryngeal area.
conclusionsGiven the prevalence of arteries and veins, particularly in areas where tracheostomies are commonly performed, we strongly advocate for routine ultrasound assessments before such procedures are performed.
