Diagnostic evaluation of intrauterine fetal deaths in Stockholm 1998–99
Bibliographic record
Abstract
BACKGROUND: To evaluate the diagnostic methods and to elucidate the etiology of intrauterine fetal death. MATERIAL AND METHODS: A prospective study was conducted on all intrauterine fetal deaths occurring in Stockholm County in 1998-99. During a 24-month period, 188 cases of intrauterine fetal death with gestational ages of > or = 22 weeks were investigated in accordance with structured test protocol. All information from antenatal and delivery records as well as all test results were entered in to an Internet-based database for continuous evaluation. RESULTS: A presumptive explanation to the stillbirth was established in 91% of the cases. The most common factors associated with intrauterine fetal death could be identified as infections (24%), placental insufficiency/intrauterine growth restriction (22%), placental abruption (19%), intercurrent maternal conditions (12%), congenital malformations (10%), and umbilical cord complications (9%). CONCLUSIONS: A relevant test protocol in cases of intrauterine fetal death reduces the number of unexplained cases to a minimum. An Internet-based register on test results of fetal deaths may enable a continuous evaluation of the diagnostic tools and etiologic factors in an ever-changing panorama. The results from the present study can serve as a base for a case-control study in Sweden.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
