Concentration of soluble intercellular adhesion molecule-1 in serum samples from patients with endometriosis collected during the luteal phase of the menstrual cycle
Bibliographic record
Abstract
BACKGROUND: Soluble intercellular adhesion molecule-1 (sICAM-1), released by endometriotic lesions, is involved in the regulation of cytotoxic processes. Altered levels of sICAM-1 in the circulation could parallel its deregulation in the peritoneal cavity. We therefore investigated whether sICAM-1 could represent a serum marker for endometriosis. METHODS: sICAM-1 levels were measured by enzyme-linked immunosorbent assay in serum samples from 176 subjects with surgically confirmed endometriosis (134 patients with stage I-II and 42 patients with stage III-IV) and 198 controls with no surgical evidence of the disease. All serum samples were collected during the luteal phase of the menstrual cycle. Detailed information about demographics, symptoms and clinical profile were collected. RESULTS: Mean levels of sICAM-1 appeared significantly reduced in patients with stage III-IV endometriosis in a crude comparison of means. However, when means were adjusted for potential confounders such as the pre-operative indication or fertility status, no significant difference between cases with stage III-IV disease and controls was observed. CONCLUSIONS: Serum levels of sICAM-1 during the luteal phase of the cycle are not able to discriminate women suffering from endometriosis from controls when confounders are taken into account. These results underline the importance of careful identification of confounders, based on patients' demographic and clinical data in studies aiming at discovering diagnostic markers for endometriosis.

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.
