NECKCHECK project: development and validation of a digital checklist for radiologic assessment of oral cavity squamous cell carcinoma.
Article in Clinical oral investigations, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesOral cavity squamous cell carcinoma (OCSCC) is one of the most common malignancies affecting the oral region and requires accurate imaging assessment for staging and treatment planning. However, variability in radiologic interpretation may lead to inconsistencies in clinical decision-making. The aim of this study was to develop and evaluate a structured radiologic checklist (NECKCHECK) to improve diagnostic accuracy and interobserver agreement in the imaging assessment of OCSCC. MATERIALS AND
methodsNECKCHECK was developed following a comprehensive narrative review of the literature focusing on relevant staging features of OCSCC using computed tomography (CT) and magnetic resonance imaging (MRI). Key radiologic parameters were organized into a digital checklist designed to guide systematic image interpretation. A concordance study was performed in which otolaryngologists independently evaluated anonymized CT and MRI examinations of patients with OCSCC, both with and without checklist support. Expert radiologist assessment served as the reference standard. Interobserver agreement was assessed using Cohen's kappa coefficient, and diagnostic accuracy was measured as the proportion of correct responses.
resultsUse of the checklist significantly improved interobserver agreement, with mean Cohen's kappa increasing from 0.44 to 0.72. Diagnostic accuracy also improved significantly, with correct responses increasing from 67.1% to 84.7% (p < 0.001). Perfect agreement was achieved for key parameters such as tumor size and depth of invasion.
conclusionsImplementation of a structured radiologic checklist improves both diagnostic accuracy and interobserver agreement in the imaging evaluation of OCSCC. CLINICAL RELEVANCE: NECKCHECK may support more standardized radiologic assessment of oral cavity squamous cell carcinoma and improve multidisciplinary clinical decision-making in oral cancer management.
