Correlation of Newly Added Dysplastic Features in the Latest WHO Diagnostic Criteria of Oral Epithelial Dysplasia with Malignant Transformation and Recurrence.
Article in Head and neck pathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundSeveral grading systems are available in the literature for grading oral epithelial dysplasia (OED), with the three-tier system and binary systems being the most commonly employed. However, these systems show variable interobserver agreement. The 2024 World Health Organisation (WHO) added new architectural and cytological features in the diagnostic criteria of OED. The present study was orchestrated to correlate the newly included architectural and cytological features with malignant transformation (MT) and recurrence potential of oral epithelial dysplasia. METHODOLOGY: After obtaining clearance from the institutional human ethical committee, 163 satisfactory cases of OED were included in the present study. Data about age, gender, site, habits, grading, serial time and event (malignant transformation and recurrence) were recorded. All cases were graded by two observers, using two different grading systems, and interobserver agreement was assessed using Kappa statistics. Malignant transformation and recurrence were correlated with the newly added features using hazard ratios (confidence interval was set at 95%). SPSS software (version 26) was used to do the analysis, and any value of ≤0.05 was considered statistically significant.
resultsA peak was noted in the fifth decade, with males more commonly affected than females. Buccal mucosa was the most commonly affected site. Kappa values for the three-tier grading system and binary system were 0.761 and 0.666, respectively, suggesting a moderate inter-observer agreement (p value < 0.001). Malignant transformation was significantly associated with expanded proliferative compartment, mitoses in maturing cells, altered keratin pattern in subsites and verrucous/papillary architecture of the epithelium, while mitoses in the maturing cells, basal cell clustering, multifocal or skip lesions, increased nuclear size, and single cell keratinization were significantly associated with recurrence potential of OED.
conclusionThe newly added features in the diagnostic criteria of oral epithelial dysplasia by WHO show prediction of MT and recurrence, and must be individually recorded to provide appropriate personalised treatment.
