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
objectiveEvaluation and correlation of 17β-Estradiol(E2) in blood and Estrogen Receptor α (ERα) and Estrogen Receptor β(ER β) in tissue of four groups divided as normal control subjects (group I), active control subjects (group II), premalignant(leukoplakia) (group III) and OSCC patients (Group IV).
methodsSubjects were divided in four groups mentioned previously and evaluated individually for 17β-estradiol(E2) in blood and ERα & ER β in tissue. The blood samples were evaluated by chemiluminescence assay and tissues samples were evaluated by Real-Time PCR for tissue analysis. Analysis of variance (ANOVA) was applied for quantitative evaluation of variables in each group followed by TukeyB test. Pearson Correlation Coefficient was used to study the correlation between the variables. Survival analysis was calculated by Kaplan-Meier Survival Analysis.
resultsThe results are indicative of statistically significant increased levels of E2 in the 4 groups by analysis of variance (p value-0.0327) followed by TukeyB test with statistically significant difference between Group VI and I (sig value-0.008) and Group VI and II (sig value-0.029). The Pearson correlation coefficient demonstrated that the mean levels of Estradiol are positively correlated with mean levels of ER α (p value- 0.030). Results did not indicate an association between survival and expression of E2, ER α and ER β.
conclusionThe levels of E2 can be used as a marker in predicting the progression of disease from normal tissue not exposed to tobacco to normal tissue exposed to tobacco to premalignant to OSCC. The ERα in tissue is positively correlated with the increased levels of E2 in serum, so ERα expression in tissue along with E2 in serum could be used to identify the subsets of patients with higher risk of developing OSCC, especially those subjects with established tobacco habit but no appreciable change in oral mucosa.
