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

Introduction: Subclinical hypothyroidism (SCH), defined by elevated thyroid-stimulating hormone (TSH) with normal thyroid hormone levels, affects approximately 3-8% of the population. Growing evidence indicates that thyroid-stimulating hormone receptor (TSHR) expression in cardiovascular tissues, together with systemic inflammation (IL-6) and oxidative stress (3-nitrotyrosine), may contribute to cardiovascular dysfunction in SCH. This study aimed to evaluate the association between TSHR gene expression and systemic biomarkers-hormonal, inflammatory, and oxidative-and to assess their predictive value for cardiovascular risk in SCH patients. Methods: A case-control design was adopted involving 150 SCH subjects and 150 age- and sex-matched healthy controls. Demographic and clinical data were collected using structured interviews. Fasting blood samples were analyzed for TSH (CLIA), IL-6, and 3-nitrotyrosine (ELISA), while TSHR gene expression was quantified using real-time PCR with GAPDH as an internal control. Statistical analyses were performed using Stata version 17.0. Results: Compared with controls, SCH patients showed significantly higher levels of TSH, IL-6, 3-nitrotyrosine, and TSHR gene expression ( Conclusion: SCH is characterized by elevated hormonal, oxidative, and inflammatory markers, with oxidative stress contributing to TSHR upregulation. TSH remains the strongest independent predictor, underscoring the hormonal-oxidative interaction in cardiovascular risk among SCH patients.
