Is hyperemesis gravidarum related to country of origin? Short report.
Bibliographic record
Abstract
manifestation of nausea and vomiting during pregnancy. Many studies have attempted to show associations between biopsychosocial stressors and hyperemesis gravidarum. Few studies, however, have looked specifically at whether ethnic origin or country of origin influence development of hyperemesis gravidarum. Hyperemesis gravidarum is usually thought to be more prevalent in Western societies. Two studies from New Zealand indicate that incidence of hyperemesis gravidarum differs according to women’s ethnic origin. No studies have looked at how the process of immigration affects the emergence of hyperemesis gravidarum. This study attempted to determine whether hyperemetic women were more likely to be born outside the province of Quebec, ie, far from where current medical care was provided, implying that immigration was an issue. The house staff of the Jewish General Hospital (JGH) had a clinical impression that it was. This is a clinical retrospective study. Subjects were patients admitted to JGH. Data were collected from charts completed between April 1992 and March 1997.

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.
