Abstract

fetched live from OpenAlex

To the Editor: Female pattern hair loss (FPHL) is a common form of hair loss affecting up to 38% of women.1 FPHL has previously been associated with medical conditions affecting fertility, including polycystic ovary syndrome (PCOS).2 However, the strength and nature of the association between FPHL and PCOS remain unclear. We conducted a systematic review and meta-analysis to evaluate the relationship between FPHL, PCOS and factors potentially associated with altered fertility.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
