Abstract
AIMS: Low serum concentrations of the insulin-sensitizing protein adiponectin predict the development of incident Type 2 diabetes (T2DM). It has recently emerged that the anti-diabetic activity of adiponectin may be mediated by its high-molecular-weight (HMW) isoform, circulating levels of which are decreased in T2DM. The relevance of decreased HMW adiponectin to incident T2DM, however, has not been assessed. Since gestational diabetes (GDM) identifies a population of young women at high risk of future T2DM (i.e. representing an early stage in the natural history of the disease), we sought to determine if decreased HMW adiponectin is a feature of GDM. METHODS: HMW and total adiponectin were measured in 121 women at the time of oral glucose tolerance testing (OGTT) in late pregnancy, following an abnormal glucose challenge test. Based on the OGTT, there were 41 women with and 80 without GDM. RESULTS: Median HMW adiponectin concentration was lower in women with GDM (3.5 microg/ml) than in those without GDM (5.5 microg/ml) (P < 0.0001). After full adjustment for covariates, mean HMW adiponectin remained significantly lower in women with GDM compared with their peers (3.6 vs. 5.3 microg/ml, P = 0.0035). HMW adiponectin was positively associated with insulin sensitivity (IS(OGTT)) (r = 0.38, P < 0.0001) and pancreatic B-cell function [insulin secretion-sensitivity index (ISSI)] (r = 0.33, P = 0.0002) and inversely related to blood glucose levels, including area-under-the-glucose-curve during the OGTT (AUC(glucose)) (r = -0.31, P = 0.0007). On separate multiple linear regression analyses, HMW adiponectin emerged as an independent determinant of AUC(glucose), IS(OGTT) and ISSI, respectively, mirroring the relationships of total adiponectin. CONCLUSIONS: HMW adiponectin is significantly decreased in women with GDM. Deficiency of HMW adiponectin may be an early event in the natural history of T2DM.

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 it
