Twin Birth and Hemolysis, Elevated Liver Enzymes, and Low Platelets (HELLP) Syndrome: A Population-Based Study
Bibliographic record
Abstract
OBJECTIVES: Although twin pregnancies are known to have higher rates of preeclampsia, the association between twin pregnancy and Hemolysis, Elevated Liver Enzymes, and Low Platelet Count (HELLP) syndrome has not been adequately studied. We assessed the association between twin pregnancy and HELLP syndrome, and also examined gestational age-specific rates of HELLP syndrome in twin and singleton pregnancies. METHODS: weeks gestation in British Columbia, Canada, from 2008/09 to 2019/20. Data on the demographic and clinical characteristics were obtained from the British Columbia Perinatal Database Registry. Logistic regression was used to estimate adjusted odds ratios and 95% CIs, adjusted for maternal age, body mass index, smoking, and other potential confounders. RESULTS: weeks gestation in singleton pregnancies. CONCLUSIONS: weeks gestation onwards.
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 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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
