## What The Sources Report

- This transition results from the progressive depletion of ovarian follicles, leading to reduced estrogen and progesterone secretion. [Zago Isabella Heloísa Rodrigues (2026); evidence level 1]
- These changes are associated with an increased risk of several chronic conditions, including cardiovascular disease, hormone-sensitive breast cancer, insulin resistance, type 2 diabetes mellitus (T2DM), and osteoporosis. [Zago Isabella Heloísa Rodrigues (2026); evidence level 1]

## How To Read This Evidence

Evidence level 1 generally reflects systematic reviews or meta-analyses. Level 2 includes randomized trials, guidelines, or public-health guidance. Level 3 usually reflects observational or narrative-review evidence. Level 4 is weaker or early-stage evidence. The level is a sorting aid, not a final quality grade.

## Practical Interpretation

There is at least one systematic-review style source in the current set, so it deserves more weight than single-study evidence. For green tea extract sleep randomized trial, the next editorial step is to add more targeted sources and separate strong findings from early or indirect evidence.

## Limits Of This First Pass

This is a small-batch MVP article. It uses the first ingested sources for this topic and should be expanded with more targeted searches, license review, and human editorial checks before being treated as a definitive review.
