A Cross-sectional Analysis of Serum Irisin Levels in Individuals with Thyroid Dysfunction Compared to the Control Population.
Article in Annals of African medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIrisin is an adipo-myokine that is released by proteolytic cleavage of the membrane protein, fibronectin type III domain-containing protein 5. Irisin is responsible for the process of browning of white adipose tissue and is known to impact thermogenesis. Owing to the similarities in action between irisin and thyroid hormones, identifying these mutual influences in the body seems to be imperative.
aimThis study aimed at investigating the association between serum irisin levels and thyroid dysfunction. METHODOLOGY: This cross-sectional study was conducted in the Department of Endocrinology, Ramaiah Medical College and Hospital, Bengaluru, India, from January 1, 2025, to May 1, 2025, among individuals greater than 18 years old with new-onset hypothyroidism or hyperthyroidism and euthyroid age- and sex-matched control population who consented to the study. Serum irisin levels were assayed and compared between groups (hypothyroid, hyperthyroid, and control). Statistical analysis was performed using SPSS version 22 and Microsoft Excel (2016). An independent t -test was used as a significant test to identify the mean difference between two quantitative variables. Categorical data were represented in frequencies and proportions. Continuous data were expressed as mean and standard deviation. Correlations were performed with the Pearson Correlation coefficient. P <0.05 was considered statistically significant.
resultsThe study included 23 euthyroid controls and 48 individuals with thyroid dysfunction (28 hyperthyroid; 20 hypothyroid). A significant difference was noted in serum irisin levels between controls and individuals with thyroid dysfunction ( P = 0.03). Further analysis depicted hypothyroid individuals showing a strong positive correlation between irisin and thyroid-stimulating hormone levels ( r = 0.382, P = 0.04).
conclusionThis study highlights the positive correlation of irisin levels in hypothyroid individuals, speculating on the possibility of irisin's role in physiological adaptations in individuals with hypothyroidism.
