Mini-clusters of potentially prodromal symptoms may identify psychiatrically well Amish children at higher risk of developing bipolar I disorder
Bibliographic record
Abstract
Egeland JA, Shaw JA, Endicott J, et al . Prospective study of prodromal features for bipolarity in well Amish children. J Am Acad Child Adolesc Psychiatry 2003;42:786–96.[OpenUrl][1][CrossRef][2][PubMed][3][Web of Science][4] Q Do frequencies of potential early prodromal clinical features for bipolar I (BPI) disorder in psychiatrically well Amish children correlate with family history, and therefore inferred risk, of BPI? ### ![Graphic][5] Design: Prospective cohort study; outcome assessors were blinded as to family history, however, it was impossible to blind data collectors. ### ![Graphic][6] Follow up period: Seven years. ### ![Graphic][7] Setting: Amish families in rural Pennsylvania, USA; 1994 to 2000. ### ![Graphic][8] People: 210 children from 27 families. 14 BPI families (100 children) had one parent with BPI. The families of same sex, psychiatrically unaffected siblings of each bipolar parent were selected as matched controls where possible. Control siblings were selected to be as close in age, marriage date, and number of children to the bipolar sibling. In the absence of a suitable matched sibling control, the family of a non-related Amish participant matched for sex, age, and family size, but without a family history of … [1]: {openurl}?query=rft.jtitle%253DJournal%2Bof%2Bthe%2BAmerican%2BAcademy%2Bof%2BChild%2Band%2BAdolescent%2BPsychiatry%26rft.stitle%253DJ%2BAm%2BAcad%2BChild%2BAdolesc%2BPsychiatry%26rft.aulast%253DEgeland%26rft.auinit1%253DJ.%2BA.%26rft.volume%253D42%26rft.issue%253D7%26rft.spage%253D786%26rft.epage%253D796%26rft.atitle%253DProspective%2Bstudy%2Bof%2Bprodromal%2Bfeatures%2Bfor%2Bbipolarity%2Bin%2Bwell%2BAmish%2Bchildren.%26rft_id%253Dinfo%253Adoi%252F10.1097%252F01.CHI.0000046878.27264.12%26rft_id%253Dinfo%253Apmid%252F12819438%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=10.1097/01.CHI.0000046878.27264.12&link_type=DOI [3]: /lookup/external-ref?access_num=12819438&link_type=MED&atom=%2Febmental%2F7%2F1%2F26.atom [4]: /lookup/external-ref?access_num=000183750800009&link_type=ISI [5]: /embed/inline-graphic-1.gif [6]: /embed/inline-graphic-2.gif [7]: /embed/inline-graphic-3.gif [8]: /embed/inline-graphic-4.gif

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.
