1 · What the graph read from it

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.

2 · The registry

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

introductionThe most common cause of hyperthyroidism, Graves' disease is a common organ-specific autoimmune disease. Selenium is an essential trace element of the human body that is mainly concentrated in the thyroid gland and is involved in the synthesis and metabolism of thyroid hormones. Most studies have shown that the level of selenium is closely related to the occurrence and development of thyroid diseases, and selenium supplementation can help improve thyroid function. This study aims to evaluate the efficacy of selenium supplementation for patients with Graves' hyperthyroidism during methimazole treatment. METHODS AND ANALYSIS: We will search the electronic databases including PubMed, Web of Science, Embase, the Cochrane Library, China National Knowledge Infrastructure, Wanfang Data and Chinese Biomedical Literature, and the time was deadline to December 2023. To evaluate the efficacy of methimazole combined with selenium supplementation in the treatment of Graves' hyperthyroidism, randomised controlled trials will be included. The Cochrane Collaboration's risk of bias tool will be used to assess the quality of all included studies, and the baseline data of all the studies are extracted by the authors. A random-effects model or a fixed-effects model is used to analyse the outcomes. The primary outcomes are the levels of selenium, triiodothyronine, free thyroxine and thyroid-stimulating hormone (TSH), whereas the secondary outcomes include TSH receptor antibody, thyroid peroxidase antibody and thyroglobulin antibody. ETHICS AND DISSEMINATION: Ethics approval is not required since no original data will be collected. The results of this study will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42023410999.
