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
Introduction: Papillary thyroid carcinoma (PTC) and colloid goiter (CG) represent the most common thyroid malignant and benign diseases, respectively. Oxidative stress is considered to have an important role in the pathogenesis of both diseases, but without sufficient and comprehensive data. The aim was to evaluate the redox profile, its influence on cell survival of PTC, comparing it with CG as a control and its relation with demographic, pathological and clinical parameters. Material and methods: We evaluated for the first time the PTC and CG tissue profile of advanced oxidation protein products (AOPP) and total thiols as parameters of redox metabolism and deoxyribonuclease I (DNase I) and deoxyribonuclease II (DNase II) activity as biomarkers of cell turnover and apoptosis. Tissue levels of biochemical parameters were quantified in PTC and CG tissue using spectrophotometric methods. Study parameters were evaluated in light of different demographic, clinical and pathological features of PTC and CG. Results: Papillary thyroid carcinoma tissue is characterized by increased antioxidant activity and a normal prooxidation level. Biochemical parameters show numerous correlations with demographic and clinical characteristics of PTC and CG patients. DNase I and II activities are dependent upon the AOPP concentration in PTC tissue. The size of CG can be predicted with combined use of AOPP, DNase I and DNase II. AOPP is the most powerful predictor of PTC capsular invasion, multicentric intrathyroid dissemination and lymph node metastasis phenotype. Conclusions: Evaluated parameters can be used for assessment of tumor redox and survival status and the clinical course of PTC and CG.
