This is a narrative review synthesizing mechanistic evidence and intervention strategies for gut microbiota in PCOS, providing expert summary rather than original data or a practice-changing trial.
A randomized double-blind trial with 96 participants showing dose-response improvements in insulin resistance, hormonal markers, and menstrual regularity over 24 weeks, but limited by single-center design, surrogate endpoints, and lack of hard clinical outcomes.
This is a published protocol for an upcoming multicenter RCT; no results are presented, only the study design and rationale for a planned comparison of diet versus metformin in PCOS.
A retrospective, cross-sectional genotyping study proposing a mechanistic pathway (MTHFR genotype → homocysteine → metabolic heterogeneity) without causal evidence; the authors acknowledge exploratory design and explicitly call for prospective validation.
This is a mechanistic review synthesizing evidence largely from rodent models and cultured systems to propose BMAL1 dysregulation as a unifying mechanism; direct causal evidence in humans is acknowledged as lacking, and clinical data are only consistent with, not proof of, the proposed dual mechanism.
A single-centre cross-sectional study with modest sample size and no control group for adipokine differences; correlational findings are hypothesis-generating rather than causal or practice-defining.
Small, uncontrolled cross-sectional study of a biomarker (SCFA levels) in follicular fluid with no healthy control group, measuring an association rather than a clinical outcome; authors acknowledge need for further studies.
A mixed mechanistic study combining human observational data with a targeted animal model, showing a significant human-animal disconnect that narrows but does not resolve the hypothesis about adiponectin and anxiety in PCOS.
