Microsomal reductase activity in patients with thyroid neoplasms.
Article in Endocrine, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveCytochrome b5-reductase (CYB5R) and cytochrome P450 reductase (CYPOR) are important for cell metabolism; however, their role in thyroid hormonogenesis and carcinogenesis has not been elucidated yet. The activity of CYB5R correlates with the metastasis in breast cancer, but there are no similar studies for CYB5R and CYPOR for thyroid tumors. The aim of this study was to elucidate the activity of CYB5R and CYPOR changes in benign euthyroid and hyperthyroid neoplasms and in papillary thyroid cancer for their potential application as biomarkers for diagnosis and prognosis prediction of thyroid cancer.
methodsThirty-six patients with thyroid diseases participated in the study. The control euthyroid nodular goiter group included ten patients; the thyrotoxic nodular or diffuse goiter group included 14 patients; the papillary thyroid cancer T1-2N0-1M0 (PTC) group included 12 patients. The activity of CYB5R and CYPOR was assessed with lucigenin-enhanced chemiluminescence stimulated by NADH and NADPH, respectively.
resultsCompared to the control euthyroid nodular goiter group, activity of CYB5R and CYPOR increased ~5 and 10 times, respectively, in toxic goiter, and 15 and 30 times, respectively, in half of cases of PTC. The change in activity of CYPOR was more pronounced compared to CYB5R. Within the PTC group, the subgroups with low and high activities of microsomal reductases were identified. Microsomal reductases in follicular adenoma was 2-4-fold less active compared to the euthyroid nodular goiter and the low-activity PTC group.
conclusionsActivity of tissue microsomal reductases varies in thyroid pathology and can be considered as a promising biomarker for differential diagnostics of benign and malignant thyroid tumors.
