Evaluating micro-computed tomography for investigation of the pediatric hyoid-larynx complex.

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
backgroundConventional CT imaging has limitations in detecting subtle fractures or soft tissue hemorrhages of the pediatric hyoid-larynx complex due to its largely unossified, cartilaginous structure, creating a diagnostic gap in forensic investigations.
objectiveTo explore the feasibility of micro-computed tomography (micro-CT) and diffusible iodine-based contrast-enhanced computed tomography (diceCT) as high-resolution imaging techniques for detailed forensic and developmental assessment of the pediatric hyoid-larynx complex. MATERIALS AND
methodsFive pediatric hyoid-larynx complex samples were obtained during forensic autopsies. Specimens were excised, fixed in formaldehyde, and scanned using micro-CT. Subsequently, samples were stained with buffered Lugol's solution and rescanned for diceCT. Imaging was performed with voxel sizes between 12-35 µm. Scans were assessed by a trained analyst and two experienced forensic (pediatric) radiologists.
resultsAll five samples were successfully imaged using micro-CT and diceCT. Ossification increased with age: the youngest sample showed minimal ossification, while the oldest showed ossification of the hyoid lesser horn and thyroid cartilage. Anatomical variants included bilateral triticeal cartilages and ossified stylohyoid ligament fragments. DiceCT enabled detailed soft tissue visualization and revealed hyperdense bundles and ossification centers within the thyroid cartilage. Staining was complete in smaller samples but limited in the largest. No traumatic injuries were detected on imaging or autopsy.
conclusionMicro-CT and diceCT offer high-resolution visualization of both ossified and soft tissue structures in the pediatric hyoid-larynx complex. These methods overcome limitations of conventional CT, demonstrating strong potential to enhance forensic evaluation of pediatric neck trauma.
