Abstract

fetched live from OpenAlex

Purpose: The aim of the current study was to evaluate the effect of melatonin administration on clinical, hormonal, inflammatory and genetic parameters in women with PCOS. Methods: The present randomized, double-blinded, placebo-controlled clinical trial was conducted among 56 patients with PCOS, aged 18-40 years old. Subjects were randomly allocated to take either 5 mg melatonin supplements (n=28) or placebo (n=28) twice a day for 12 weeks. Results: Melatonin administration significantly reduced hirsutism (β -0.47; 95% CI, -0.86, -0.09; P=0.01), serum total testosterone (β -0.11 ng/mL; 95% CI, -0.21, -0.02; P=0.01), high-sensitivity C-reactive protein (hs-CRP) (β -0.61 mg/L; 95% CI, -0.95, -0.26; P=0.001) and plasma malondialdehyde (MDA) levels (β -0.25 µmol/L; 95% CI, -0.38, -0.11; P<0.001), and significantly increased plasma total antioxidant capacity (TAC) levels (β 106.07 mmol/L; 95% CI, 62.87, 149.28; P<0.001) and total glutathione (GSH) (β 81.05 µmol/L; 95% CI, 36.08, 126.03; P=0.001) compared with the placebo. Moreover, melatonin supplementation downregulated gene expression of interleukin-1 (IL-1) (P=0.03) and tumor necrosis factor alpha (TNF-α) (P=0.01) compared with the placebo. Conclusions: Overall, melatonin administration for 12 weeks to women with PCOS significantly reduced hirsutism, total testosterone, hs-CRP and MDA, while increased TAC and GSH levels. In addition, melatonin administration reduced gene expression of IL-1 and TNF-α.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
