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
Objectives: This study aims to evaluate the effectiveness and role of telomere length measurements in leukocytes, plasma free cell DNA (cfDNA), and biopsy cells, along with technetium-99m (Tc-99m) methoxyisobutylisonitrile (MIBI) scintigraphy, as non-invasive methods for diagnosing malignant thyroid lesions. Methods: Data from 128 patients, who underwent ultrasound, Tc-99m MIBI scintigraphy, and fine-needle biopsy with a preliminary diagnosis of malignant thyroid nodules, were analyzed. In 98 patients, telomere lengths in leukocytes (from blood), cfDNA (from plasma), and biopsy cells were measured using the quantitative polymerase chain reaction method, and the relative telomere/single copy gene (T/S) ratio was calculated. Based on cytological examination results, patients were categorized into three groups: malignant, benign, and suspicious. Group differences were analyzed using the Kruskal-Wallis and Chi-square tests, and correlations between variables were examined with Spearman correlation analysis. Results: The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of Tc-99m MIBI scintigraphy for diagnosing malignant thyroid nodules were 64.70%, 79.16%, 29.72%, 83.51%, and 67.96%, respectively. While these results align with the literature, the positive predictive value was notably lower. No significant differences were observed in telomere lengths (T/S ratios) in leukocytes, plasma, or tissue between the groups. Conclusion: Tc-99m MIBI scintigraphy demonstrates reasonable diagnostic accuracy for identifying malignancy in thyroid nodules. Contrary to limited reports, telomere length measurements may not be a reliable method for predicting thyroid malignancy. Larger studies are needed to further explore these findings.
