Comparison of vitamin D, parathyroid hormone, and body composition in obese premenopausal and postmenopausal women.
Article in Endocrine, 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
purposeWe aimed to investigate the associations of serum vitamin D and parathyroid hormone (PTH) with body composition parameters, including bone weight and mineral content, in obese premenopausal and postmenopausal women.
methodsIn this retrospective study, 200 pre-menopausal and 200 post-menopausal obese women were evaluated. Body composition was assessed using a bioelectrical impedance analyzer (TANITA-48M), and biochemical parameters were measured by standard laboratory methods.
resultsThe mean serum vitamin D level was significantly lower in pre-menopausal women compared with post-menopausal women (16.91 ± 13.17 vs. 22.59 ± 16.49 ng/mL, p < 0.05). Overall, 83.75% (n = 335) of the study population had vitamin D deficiency or insufficiency, while only 16.25% (n = 65) demonstrated normal vitamin D levels. BMI did not differ significantly between the two groups (p > 0.05). In pre-menopausal women, serum vitamin D levels were negatively correlated with PTH and mineral content. In post-menopausal women, vitamin D levels showed a negative correlation with BMI, body weight, body fat percentage, and PTH (p < 0.05).
conclusionsThe prevalence of hypovitaminosis D was remarkably high (83.75%) among obese women. Moreover, declining vitamin D levels were associated with increased body weight and adiposity, as well as elevated PTH.
