To Determine the Immune Check Point Protein Expression CTLA-4 and VISTA With Clinical and Pathological Staging of Potential Oral Malignant Lesions by Immunohistochemistry Analysis.
Article in Asian Pacific journal of cancer prevention : APJCP, 2025. 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
introductionThe immune microenvironment is essential in the development of leukoplakia. Which is a potentially precancerous lesion with increased chances of evolving into oral squamous cell carcinoma (OSCC). One of the most significant co-stimulatory molecules involved in the negative regulation of T cells during carcinogenesis is the immunological check point protein V-domain Ig Suppressor of T-cell Activation (VISTA), also known as CTLA-4. The VISTA and CTLA-4 serves as a emerging new biomarker in early detection and to determine malignant potential of leucoplakia. MATERIAL AND
methodTissue samples from patients with suspected oral malignant lesions were analyzed using immunohistochemistry (IHC). We used established scoring methods to analyze the expression levels of CTLA-4 and VISTA. Clinical finding and histopathological grading were established. The association between the patterns of protein expression and the clinicopathological features was discovered by statistical analysis.
resultVISTA expression varied among the different dysplasia grade with a non-linear relationship observed between VISTA expression and the severity of dysplasia. There was a progressive rise in CTLA 4 positivity that paralleled the severity of dysplasia.
conclusionCTLA 4 expression could serve as a helpful indicator for determining the risk of malignant transformation in oral potentially malignant disorders.
