Abstract

fetched live from OpenAlex

Ectopic pregnancy occurs when a fertilized ovum implants outside the endometrial lining of the uterine cavity. Ectopic pregnancy is most commonly found in the fallopian tube but may also occur in the cervix, cesarean scar, ovary, or abdominal cavity. Ectopic pregnancy accounts for up to 13% of pregnancy-related deaths. Given the high degree of maternal mortality, recognizing an ectopic pregnancy is crucial for patient management. Clinical signs and symptoms can be nonspecific, but history of pelvic pain, vaginal bleeding, and no visualization of an intrauterine gestational sac in a patient with positive beta-human chorionic gonadotropin should raise the suspicion of an ectopic pregnancy. The place of implantation ultimately dictates treatment. Ultrasound is the imaging modality of choice for diagnosing ectopic pregnancy. This article explores the various subtypes of ectopic pregnancy and their concomitant sonographic appearances.

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.
