Prevalence of Tongue Lesions in the Namakkal and Erode Districts: A Prospective Study.
Article in Cureus, 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
Background Lesions of the tongue are markers of several systemic diseases and mirror the general health. In the Namakkal and Erode districts of Tamil Nadu - regions with high tobacco/areca nut usage and limited oral health infrastructure - prevalence data on tongue lesions remain sparse. Aim This study aimed to find out how frequently common tongue lesions occur in patients from these areas. Methods A total of 1,250 patients were examined, of which 880 presented with various tongue lesions. Demographic details and clinical examination findings of the lesions were recorded in a spreadsheet and subsequently analyzed using SPSS version 26.0 (IBM Corp., Armonk, NY, USA). Results The study population predominantly comprised middle-aged adults (31-50 years), with a male predominance (53.2%). Geographic tongue (32.5%) and fissured tongue (24.3%) were the major benign tongue lesions observed among others. Geographic tongue was almost equally prevalent in males (31.6%) and females (33.5%). Fissured tongue was more common in males (26.1%). Anemic glossitis was notably higher in females (18.0%) compared to males (8.1%). The prevalence of potentially malignant disorders in the study population was relatively low, affecting 8.2% (n = 72) of participants. Conclusion The result of the present study revealed that the majority of the tongue lesions were benign rather than malignant. Despite the limitations, this study provided essential data from the Namakkal and Erode districts of Tamil Nadu outpatients. Age-, gender-, and habit-stratified results emphasized the necessity of tailormade approaches for the integration of educational, preventive, and treatment-oriented approaches into public health campaigns to reduce progression risks in high-vulnerability cohorts.
