Whether black seed would improve outcomes in the context of polycystic ovary syndrome (PCOS).

The researchers assessed the following:

• Menstrual cycle disorders: infrequent periods, the absence of periods, heavy periods, prolonged periods, or bleeding between periods (as assessed based on interviews with participants)
• Hirsutism (as assessed with the Ferriman-Gallwey score)
• Ovarian volume and endometrial thickness (as assessed on ultrasound)
• Hormone levels (DHEA, DHEA-S, testosterone, LH)
• Anthropometric measurements (weight, BMI, waist, hip, waist-hip ratio)

The effect of supplementation with herbal tea on anthropometric and biochemical parameters in the context of polycystic ovary syndrome (PCOS).

The following outcomes were assessed:

• Anthropometrics: weight, BMI, waist circumference, hip circumference, waist-hip ratio, and body fat
• Biomarkers of glycemic control: fasting glucose, fasting insulin, and the ratio of fasting glucose to fasting insulin
• Hormones: total testosterone, dehydroepiandrosterone sulfate (DHEAS), follicle-stimulating hormone (FSH), and luteinizing hormone (LH)

The effects of early time-restricted eating (eTRE) with or without supplemental probiotics in the context of polycystic ovary syndrome (PCOS).

The primary outcome was the change in weight. The secondary outcomes included waist circumference, acne severity, hirsutism, hormone levels (i.e., total testosterone, DHEA, sex hormone binding globulin), blood lipids (e.g., VLDL-C), and biomarkers of glycemic control (e.g., HOMA-IR).

The effect of a vegan diet on the following outcomes, in the context of breast cancer:

• Weight and BMI
• Blood lipids (total cholesterol, LDL-C, HDL-C) and triglycerides)
• Blood pressure
• Glycemic control (i.e., blood glucose and insulin levels)
• Hormone levels (sex hormone binding globulin, or SHBG; total testosterone, free testosterone, DHEA, IGF-1, IGFBP-3)
• Complete blood count (e.g., white blood cell count)
• Cancer progression markers (CA 27.29, CA 15-3, CEA)

The effects of high-protein diets (HPDs) on markers of cardiometabolic and reproductive hormonal health in women with polycystic ovary syndrome (PCOS).

HPDs were defined as diets in which protein supplied at least 25% of total energy intake. Balanced diets (BDs) were diets in which protein supplied less than 25% of total energy intake.

The outcomes assessed included body weight, BMI, waist circumference, fasting glucose, fasting insulin, HOMA-IR, total cholesterol, LDL-C, HDL-C, triglycerides, total testosterone, DHEAS, sex hormone binding globulin, and the free androgen index.
