Investigating geographic tongue severity: a cross-sectional study on symptoms and potential risk factors.
Article in BMC oral health, 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
backgroundGeographic tongue (GT) is a benign, recurrent inflammatory condition marked by atrophic and erythematous lesions, often asymptomatic but sometimes causing discomfort. This study evaluated some potential etiological and risk factors influencing Geographic Tongue Area and Severity Index (GTASI) and the relationship between GTASI scores and symptoms.
methodsA total of 163 GT patients (100 females [61.35%], 63 males [38.65%]) were assessed using the GTASI, which incorporates erythema, white halo, and fissured tongue (FT) scores. Statistical analyses investigated relationships between GTASI, symptoms, family history, tobacco using, allergy or atopy and medication, Categorical variables were analyzed using the chi-square test, while numerical variables were compared using the Mann-Whitney U test. A p-value of < 0.05 was considered statistically significant.
resultsWhile GT severity showed no significant relationship with gender (p = 0.694), smoking (p = 0.907), allergic conditions (p = 507), medication (p = 0.364) or family history (p = 591). Among participants, 106 (65%) reported symptoms. A total of 137 patients (84%) had at least one fissured tongue lesion associated with GT. Higher FT scores were linked to an increased likelihood of symptoms (p = 0.048). Conversely, erythema scores were not associated with symptoms (p = 0.943).
conclusionThe study did not identify risk factors influencing overall GTASI scores. However, symptom presence is significantly associated with fissured tongue rather than GT severity suggesting that clinicians should focus on fissured tongue when evaluating symptomatic patients. Further longitudinal studies and microbiological assessments are warranted to explore the underlying mechanisms and progression of symptomatic GT.
