Feature-Level Insights into the Progesterone-Estradiol Ratio in Postmenopausal Women Using Explainable Machine Learning
This study leveraged explainable AI (XAI) to unravel the complex interplay of hormonal, anthropometric, and metabolic factors influencing the progesterone-estradiol (P4:E2) ratio in postmenopausal women. By using XGBoost and SHAP values, we identified key predictors and their nonlinear contributions, providing actionable insights for understanding and potentially modulating hormone balance relevant to conditions like endometrial and breast cancer risk.

Hormonal Dynamics in Postmenopause
Understanding the balance of progesterone and estradiol (P4:E2 ratio) is crucial in postmenopausal women, as disruptions are linked to endometrial and breast cancer risk. This study identifies key hormonal predictors and their nonlinear relationships, offering a nuanced view beyond individual hormone levels. The model highlights the distinct regulatory pathways of estradiol and progesterone.
FSH (0.213)
Most influential predictor of P4:E2 ratio, indicating critical endocrine adaptation.
Metabolic & Inflammatory Influences on Hormone Balance
Systemic metabolic and inflammatory states significantly modulate the P4:E2 ratio. CRP, a marker of low-grade inflammation, and total cholesterol emerged as key non-hormonal predictors, demonstrating complex, nonlinear associations. These findings suggest that addressing metabolic and inflammatory health can indirectly improve hormonal balance and potentially mitigate disease risk.
| Predictor | Impact on P4:E2 Ratio | Key Finding |
|---|---|---|
| C-Reactive Protein (CRP) |
|
Indicates context-dependent effects of inflammation, challenging linear assumptions. |
| Total Cholesterol |
|
Highlights cholesterol as a key metabolic predictor, particularly for progesterone levels. |
Dietary & Anthropometric Factors in Hormone Regulation
Waist circumference, a measure of central adiposity, was a strong negative predictor of the P4:E2 ratio, primarily due to its association with elevated estradiol. Dietary variables showed more modest, nonlinear effects. These findings emphasize the role of lifestyle factors in shaping postmenopausal hormonal dynamics, with implications for weight management and dietary recommendations.

Explainable AI Application in Biomedical Research
The use of XGBoost and SHAP values enabled the identification of complex, nonlinear relationships and feature contributions that traditional statistical methods might miss. This XAI approach provides transparent, data-driven insights into hormonal regulation, setting a blueprint for future biomedical studies seeking accurate predictions alongside mechanistic understanding.
Case Study: Personalized Hormone Management
An AI-driven platform could leverage these insights to provide personalized risk assessments for postmenopausal women based on their individual hormonal, anthropometric, and metabolic profiles. For example, a woman with a high waist circumference and specific CRP levels might receive tailored recommendations for diet and exercise to optimize her P4:E2 ratio, potentially reducing her risk for endometrial proliferation.
Outcome: Improved patient stratification, targeted preventative interventions, and enhanced clinician understanding of complex endocrine interactions.
