Abstract

fetched live from OpenAlex

A few years after coming to the market, the first generation of oral contraceptive pills (OCPs) were linked to significant risk of venous thromboembolism (VTE). This increased risk was blamed on the presence of the estrogen-like compounds in these agents. Therefore, the efforts were initiated to decrease the VTE risk of OCPs by lowering the delivered estrogen content by adding progestins such as levonorgestrel to these products, which led to production of the second generation of OCPs. Thereafter, the third generation of these agents with lower doses of progesterone-like compounds with contraceptive efficacy was released. They contain the new progestins such as Drospirenone, Norgestimate, Desogestrel and Gestodene (1-3). Â

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
