Abstract

fetched live from OpenAlex

Twenty-eight cases of fetal hydrops are reported. A diverse aetiology was found. Fetal therapy was undertaken in 12 (42.9%). The overall survival rate was 36.8% (excluding elective terminations). However, when normal fetuses presenting from 20 weeks were considered, the survival rate was 64%. The results were combined with those of two other studies (making a total of 182 cases with fetal hydrops) to ascertain the value of pleural effusions in predicting outcome in such cases. In the 143 cases that did not end in a therapeutic termination of pregnancy, fetal pleural effusions predicted death (fetal or neonatal) with a sensitivity of 67%, a specificity of 53%, a positive predictive power of 68%, a negative predictive power of 52% and an overall accuracy of 62%.

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.

Not 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.
