Assessment of Basic Skills in Ultrasound-Based Neuraxial Access-A Protocol of a Study Gathering Validity Evidence.

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
backgroundNeuraxial access procedures, such as spinal blocks, are routine but can be challenging in for example, obese, pregnant, and elderly patients. Ultrasound-based techniques offer a promising alternative, yet standardized assessment tools for evaluating competence are lacking. This study aims to develop and gather validity evidence for a simulation-based assessment tool in ultrasound-assisted and ultrasound-guided neuraxial access, and establish a credible pass/fail score.
methodsA prospective study will be conducted at the Simulation Center, Odense University Hospital, Denmark, and at various anaesthesia departments. Using a low-fidelity mannequin and ultrasound probe, participants with varying experience levels (novices, intermediates, and experienced) will complete both ultrasound-assisted and ultrasound-guided spinal block procedures. Messick's framework of validity, which includes five key sources: content, response process, internal structure, relations to other variables, and consequences of testing, will be used to gather validity evidence for the test. Video recordings of performances will be assessed by blinded raters.
resultsThis study will provide evidence for a simulation-based assessment tool for ultrasound-based neuraxial access. Validity evidence will be gathered to ensure the tool accurately measures what is intended and to establish a credible pass/fail standard.
conclusionThe study addresses a gap in neuraxial access training by developing an objective, simulation-based assessment tool for ultrasound-based procedures in spinal anesthesia. This tool will contribute to structured, competency-based training in ultrasound-based neuraxial access.
