Abstract
Commentary on: Boekholdt SM, Arsenault BJ, Mora S, et al. Association of LDL cholesterol, non-HDL cholesterol, and apolipoprotein B levels with risk of cardiovascular events among patients treated with statins: a meta-analysis. JAMA 2012;307:1302–9.[OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] Each very-low-density lipoprotein and low-density lipoprotein (LDL) particle contains one molecule of apolipoprotein B (apoB). Increased numbers of cholesterol-depleted LDL particles are common in patients with hypertriglyceridaemia, premature vascular disease, obesity and type-2 diabetes mellitus and much in vitro and in vivo evidence indicates cholesterol-depleted LDL particles are at least as atherogenic as larger, more cholesterol-replete LDL particles.1 Nevertheless, … [1]: {openurl}?query=rft.jtitle%253DJAMA%26rft.stitle%253DJAMA%26rft.issn%253D0002-9955%26rft.aulast%253DBoekholdt%26rft.auinit1%253DS.%2BM.%26rft.volume%253D307%26rft.issue%253D12%26rft.spage%253D1302%26rft.epage%253D1309%26rft.atitle%253DAssociation%2Bof%2BLDL%2Bcholesterol%252C%2Bnon-HDL%2Bcholesterol%252C%2Band%2Bapolipoprotein%2BB%2Blevels%2Bwith%2Brisk%2Bof%2Bcardiovascular%2Bevents%2Bamong%2Bpatients%2Btreated%2Bwith%2Bstatins%253A%2Ba%2Bmeta-analysis.%26rft_id%253Dinfo%253Adoi%252F10.1001%252Fjama.2012.366%26rft_id%253Dinfo%253Apmid%252F22453571%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/external-ref?access_num=10.1001/jama.2012.366&link_type=DOI [3]: /lookup/external-ref?access_num=22453571&link_type=MED&atom=%2Febmed%2F18%2F2%2F73.atom [4]: /lookup/external-ref?access_num=000301978400026&link_type=ISI

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedLabeled directly by 2 models reading the full record.
The models disagree on parts of this classification; every voice is preserved in the section at the end of the page.
