Leptin and thyroid hormones in beta-thalassemia major: A cross-sectional study.
Article in Caspian journal of internal medicine, 2025. 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
Background: Hypothyroidism and leptin deficiency are two common endocrinopathies in β-thalassemia major patients (β-TM). Changes in leptin levels may lead to changes in thyroid hormone levels in thalassemia patients through suppression of the hypothalamus-pituitary-thyroid axis. Hence, we aimed to evaluate their correlation in β-TM patients. Methods: A cross-sectional study was conducted on transfusion dependent β-thalassemia patients receiving chelation treatment between 2018 and 2019. Tri-iodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), and leptin were measured for each participant. Data analyzed by SPSS, p< 0.05 was considered as significant. Results: One hundred and twenty-six β-TM patients aged between 10 and 30 years old participated in the study, including 55 (43.7%) females and 71(56.3%) males. TSH abnormality was prevalent among 13 (23.6%) females and 10(14.1%) males. Leptin level was significantly lower in males (6.65±7.27 VS 2.41±2.79, p<0.01). TSH was correlated with leptin in all (r=0.393, p<0.01), females (r=0.387, p<0.01), males (r=0.387, p<0.01), adolescents (r=0.512, p<0.01), young adults (r=0.287, P=0.01), underweights (r=0.483, p<0.01) and normal weight (r=0.301, P=0.03) thalassemia patients. T4 was correlated with leptin in all (r=0.201, p=0.02), females (r=0.281, P=0.03), males (r=0.281, P=0.03), and adolescents (r=0.280, P=0.03) β-TM patients. T3 did not correlate with leptin in all groups of the patients. Conclusion: In summary, leptin levels were significantly lower in males, and TSH abnormality was common in both genders. Therefore, screening for endocrine issues may benefit these people. Furthermore, leptin exhibited a correlation with TSH and T4. This may support the role of leptin on thyroid function in β-TM patients.
