Predictive Value of the Loss of pRb Expression in the Malignant Transformation Risk of Oral Potentially Malignant Disorders: A Systematic Review and Meta-Analysis.
Review in Cancers, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveThe aim of this systematic review and meta-analysis was to qualitatively and quantitatively evaluate the current evidence on the significance of the loss of early stages of oral carcinogenesis in lesions diagnosed according to clinical and/or histopathological criteria and their evolution to oral cancer. MATERIALS AND
methodsWe searched MEDLINE (through PubMed), Embase, Scopus and Web of Science for primary-level studies published before November 2024, designed as prospective or retrospective longitudinal cohorts, and not restricted by language or publication date. The risk of bias was critically assessed using the QUIPS tool. Meta-analyses, heterogeneity exploration, sensitivity and small-study effect analyses were conducted.
resultsThe inclusion criteria were met by six primary-level studies, which recruited 330 patients with OPMDs with follow-up data. The loss of pRb expression, assessed through immunohistochemistry, was significantly associated with a higher malignant transformation risk of OPMDs (RR = 1.92, 95%CI = 1.25-2.94, CONCLUSSION: The present systematic review and meta-analysis supports that the loss of expression of the tumor suppressor pRb, assessed through immunohistochemistry, is a predictor of the malignant transformation risk of oral leukoplakias. Future studies are needed in other OPMDs following the recommendations provided based on current evidence gaps.
